Wiring anything into a vehicle, especially a camera system, can feel like wrestling a greased octopus. You buy the fancy ARB kit, full of promise, only to stare at a spaghetti junction of wires and wonder if you need a degree in electrical engineering. I’ve been there, more times than I care to admit. My first attempt at installing a reverse camera, not even an ARB one, involved a lot of swearing and a questionable connection that lasted precisely three weeks before it decided to take a permanent nap.
So, when it came to figuring out how to install an ARB reverse camera, I approached it with a healthy dose of skepticism and a toolbox that’s seen better days. The goal here isn’t some corporate-speak walkthrough; it’s about getting that damn camera working without setting your rig on fire or blowing a fuse on day one.
This isn’t about the shiny marketing; it’s about the actual nuts and bolts, the bits that make you want to throw the whole damn thing out the window. We’re talking about real-world application, the kind that happens in your driveway with questionable lighting and a limited supply of patience. Let’s get this done.
Getting Started: What You Actually Need
Forget the glossy brochures for a minute. When you’re staring down the barrel of how to install an ARB reverse camera, you need to know what’s in the box and what’s NOT. ARB usually gives you the camera, the monitor, and the primary wiring harness. What they *don’t* always give you, or what you might need to supplement, are things like a good set of wire strippers (don’t use your teeth, I’ve tried), some quality electrical tape or, better yet, heat-shrink connectors, and maybe a grommet if you’re drilling a new hole through the firewall. I once spent around $150 on a fancy ‘universal’ wiring kit that turned out to be utterly useless for my specific truck, forcing me to run back to the auto parts store in a panic.
Seriously, the quality of your electrical connections is paramount. Bad connections are the silent assassins of automotive electronics, leading to intermittent failures or, worse, short circuits. The ARB camera system, like most good ones, relies on solid power and ground. Don’t skimp on this. Using those little orange wire nuts that come with some cheap kits? Yeah, avoid those like a bad ex at a family reunion.

The Wiring Saga: Power, Ground, and That Pesky Trigger Wire
Most ARB reverse camera systems will have a main power feed, a ground, and often a trigger wire. The trigger wire is key if you want the camera to automatically switch on when you put the vehicle in reverse. This is where things can get a bit fiddly. You need to tap into the reverse light circuit. For my old Holden Colorado, this meant hunting down the reverse light wire in the tailgate harness. It’s usually a bright color, but honestly, it’s like a scavenger hunt designed by a sadist.
Now, here’s a contrarian opinion: some people say you *must* use the supplied trigger wire for the camera to function. I disagree, and here is why: on several setups I’ve done, the monitor has a simple on/off switch, and I’ve just hardwired the camera to constant 12V power. The monitor then just stays on when I want it to, or I flip the switch. It’s less about the automatic function, which can sometimes be annoying if you’re just parking the car for a second, and more about having direct control. Is it the ‘correct’ way? Probably not according to the manual. Does it work and give me the visual I need when I need it? Absolutely. My truck’s reverse lights have a slight delay in coming on anyway, so the auto-trigger never felt particularly smooth. I’ve had this setup for over two years now, with no issues whatsoever.
You’ll want to find a good 12V source that’s switched with the ignition, or a constant 12V source if you don’t care about the camera running when the engine is off (which I generally don’t recommend for battery drain reasons). Finding a good ground point is just as important. Look for a clean, unpainted metal surface on the vehicle chassis. Scrape away any paint or rust to get a solid metal-to-metal connection. A loose ground is as bad as a loose hot wire. The feel of a solid connection, where the screw or bolt bites into the metal with satisfying resistance, is your cue that you’ve got a good ground.
Locating the Reverse Light Wire
This is where a multimeter becomes your best friend. With the ignition on and the transmission in reverse, probe the wires in the loom connected to your taillight assembly. You’re looking for a wire that shows approximately 12V when reverse is engaged and drops to 0V when it’s not. It’s a bit like trying to find a specific note in a chaotic orchestra; you need to listen for the right signal.
Running the Cables: Firewall and Bodywork
The main cable from the camera to the monitor needs to be routed carefully. Many ARB kits come with a decent length of cable, but you’ll need to get it from the camera at the rear of your vehicle into the cabin. This usually involves passing it through the firewall. If you’re lucky, you might have an existing grommet that’s not being used. If not, you’ll need to drill a hole, and for the love of all that is holy, use a grommet to protect the cable from chafing against the metal. The smell of burning plastic is not a good sign when you’re routing wires.
I remember once I was running a cable for a winch and I thought I could just push it through a small gap without a grommet. Big mistake. About six months later, I was driving in the rain and suddenly my winch started trying to spool itself out. Sparks were flying. That chafed wire was the culprit. It was a messy, dangerous situation that cost me hours of troubleshooting and a new set of cables. Don’t be like me. Use a grommet.
The actual ARB camera cable itself is usually quite thin and flexible, designed to snake through tight spaces. Getting it under trim panels and along the chassis rails is relatively straightforward, but patience is key. Don’t force it; work it. Think of it less like brute force and more like guiding a shy snake into its new home.

Mounting the Camera and Monitor
The ARB camera itself is typically designed to be mounted above the number plate or in a similar discreet location. Clean the mounting area thoroughly. Dust and dirt will prevent the adhesive backing (if it has one) or the screws from getting a good purchase. Make sure it’s positioned so you get a clear, unobstructed view of what’s behind you. You don’t want the spare tire or a tow hitch permanently blocking your vision.
The monitor placement is largely personal preference, but it needs to be somewhere you can see it easily without taking your eyes off the road for too long. Dash-mounted options are common, but some people prefer a suction-cup mount on the windscreen. Whatever you choose, make sure it’s secure. A monitor bouncing around on the dash is distracting and frankly, annoying. I’ve tried suction cups that fail in the sun, leaving the monitor to take a nosedive. Stick with a more permanent solution if possible, or at least one with a strong, reliable grip.
Testing and Troubleshooting
Before you button everything up, do a test run. Turn the ignition on, put the vehicle in reverse, and check your monitor. Do you have an image? Is it clear? Is it upside down? (Some cameras have a setting for this). If it’s not working, don’t panic. Most issues stem from power or ground connections. Double-check your wiring. Are the connections secure? Is the polarity correct? Is the trigger wire actually connected to the reverse light circuit?
A common issue I’ve seen, and experienced myself, is a flickering image. This is almost always a poor ground connection or a loose power connection. It’s like trying to have a conversation in a room with bad acoustics – the signal gets muddled. For example, I spent a solid hour troubleshooting a flickering camera on my mate’s ute, only to find the earth wire had vibrated loose from the chassis mount. A quick tighten, and it was crystal clear. Another thing to check is the video cable itself. Ensure it’s plugged in securely at both ends. A slightly dislodged cable can cause partial signal loss or a completely black screen.

People Also Ask
What Is the Best Position for a Reverse Camera?
For most vehicles, mounting the camera above the license plate offers the widest and clearest view of the area directly behind your bumper. Ensure it’s not obscured by the spare tire, tow bar, or any other accessories. Ideally, it should be centered and at a height that captures as much of the ground as possible, giving you a good sense of distance to obstacles.
Do I Need to Connect the Trigger Wire on My Arb Reverse Camera?
The trigger wire is for automatic activation. When your vehicle’s reverse lights come on, the trigger wire signals the ARB monitor to display the camera feed. If you prefer manual control or your monitor has a simple on/off switch, you can often bypass the trigger wire and simply power the monitor separately, turning it on when needed.
Can I Install a Reverse Camera Myself?
Yes, you absolutely can install a reverse camera yourself, even an ARB unit. While it involves working with vehicle wiring, it’s generally a manageable DIY project if you’re comfortable with basic tools and following instructions. Take your time, double-check your connections, and use quality materials for a reliable installation.
How Do I Run the Cable for My Arb Reverse Camera Through the Firewall?
You’ll need to locate a suitable opening in the firewall, often a rubber grommet that already exists. If none are available, you might need to drill a new hole and then install a rubber grommet to protect the cable from sharp metal edges. It’s vital to ensure the cable is protected to prevent it from shorting out or chafing through over time.
How Long Should the Arb Reverse Camera Cable Be?
ARB reverse camera kits typically come with a cable long enough to accommodate most standard 4×4 vehicles, including dual-cab Utes and larger SUVs. The length is usually around 7-10 meters, which should be sufficient to run from the rear bumper, through the vehicle’s interior, and up to the dashboard or A-pillar where the monitor is mounted.
Arb Camera vs. Other Brands: My Take
Look, ARB makes tough stuff. Their reverse cameras are generally built to last. The image quality is usually decent, not mind-blowing like some high-end aftermarket units, but perfectly adequate for backing up a trailer or parking in a tight spot. The build quality feels solid; you know it’s not going to fall apart after a few dusty tracks. However, you’re paying a premium for the ARB name.
Honestly, for the price of some ARB kits, you could probably get two or three decent quality cameras from less premium brands. I’ve used a few different brands over the years, and for basic functionality, many of them perform just as well. The difference often comes down to the ruggedness of the housing and the long-term reliability in harsh conditions. If you’re doing extreme off-roading where your rig is getting absolutely hammered, an ARB might be worth it. For daily driving and occasional towing, a good quality generic unit might save you a few hundred bucks. I spent around $180 testing five different brands before settling on one I liked, and it wasn’t the ARB.
| Feature | ARB Reverse Camera | My ‘Tried & True’ Alternative | Verdict |
|---|---|---|---|
| Build Quality | Excellent, rugged and weather-sealed. Feels built to survive an apocalypse. | Good, decent weatherproofing but feels less substantial. | ARB wins hands down for pure toughness. |
| Image Quality | Clear, good color representation. No complaints for typical use. | Very good, sometimes slightly sharper in low light. | Both are good enough; personal preference for nuance. |
| Price | Premium. You pay for the ARB badge and warranty. | Mid-range. Offers great value for the performance. | The alternative is significantly cheaper and delivers 90% of the experience. |
| Installation Complexity | Standard for a vehicle camera system. | Identical. Wiring is wiring, regardless of brand. | Tie. No inherent advantage for either. |
Verdict
So, how to install an ARB reverse camera isn’t rocket science, but it does demand a bit of patience and attention to detail. Don’t rush the wiring; that’s where most people get into trouble, myself included more than once. Take the time to find good power and ground sources, use quality connectors, and run your cables neatly and securely. A well-installed camera is a huge asset for safety and convenience, especially when you’re maneuvering a large vehicle or towing.
If you’re doing this on a budget, remember that while ARB is a solid choice, there are other excellent options out there that won’t drain your wallet quite as much. The key is understanding what makes a camera system work: reliable power, a solid ground, and a clean video signal. Don’t be afraid to test your connections with a multimeter, and for goodness sake, use a grommet when running wires through the firewall.
Ultimately, getting that clear view behind you is the goal. Whether you go with ARB or a more budget-friendly option, the principles of a good installation remain the same. Double-check everything before you put all the trim back on. That one forgotten screw or loose connection can be a real headache down the line.
