Who this is for (and when not to DIY)
If you drive a sedan, SUV, or hatchback and want to run a rear dash cam cable yourself, this guide walks you through it. You’ll be prying trim panels with plastic tools and feeding cable through rubber grommets — if that sounds like something you can tackle, you’re good to go.
But think twice about DIY if you can’t find your vehicle’s owner’s manual or if you’re worried about snapping fragile trim clips. Some interior panels break easily, and once they’re broken, they’re a pain to fix.
Also, many vehicles have side airbags in the A-pillar. Never run the cable across the face of the pillar — route it behind the airbag housing along the inner edge of the trim. And don’t fully remove pillar covers unless you’re experienced; the clips break easily. Just pry the cover enough to tuck the cable behind it.

Buy the right cable length first
Standard 6 m rear-camera cables are often included with dash cams, but they can fall short on longer vehicles or if you choose a winding route. If you have to go around obstacles, that extra distance adds up quickly.
Before you start pulling wires, plan your exact path. Measure the distance from the front camera to the rear camera, making sure to include all the loops and turns around pillars and grommets.
Stock 6 m cables often run short on longer vehicles or winding routes. If your planned path is long, an 8 m cable can save you from coming up a foot or two short.

Choose the route: headliner vs lower interior
You generally have two main paths to choose from when running your wire.
- The headliner/weather-strip route: This is the quickest method. You simply peel back the rubber weather stripping along the edge of the door or window, insert the cable, and press the seal back into place. It is very easy to undo if you change your mind later.
- The lower-interior route: This method involves running the wire under the carpet and behind the kick panels (the plastic covers near your feet). While it takes more work, it is widely considered safer because it avoids the side-airbag zones entirely.
A-pillar safety around airbags
The A-pillar is the vertical support between your windshield and your side window. Many vehicles have side-curtain airbags hidden inside this pillar.
Never run the cable across the face of the pillar where an airbag would deploy. Instead, route the wire behind the airbag module or along the outer edge of the pillar, following the existing factory wiring.
When working in this area, do not fully remove the pillar cover unless you are experienced. The plastic clips that hold the cover in place break easily. It is much safer to pry the cover just enough to tuck the cable behind it.
Getting through the hatch/trunk grommet
If you’ve got an SUV or hatchback, you need to get the wire from the car body into the rear liftgate. The cleanest way is through the factory rubber grommet — that’s the rubber hose connecting the rear windshield wiring to the chassis.
Using this grommet keeps the wires invisible and prevents them from getting pinched by the trunk hinge. Because these rubber tubes can be very tight, try these tips:
- Use a guide: Tape your cable to a rigid wire (like a coat hanger, fishing wire, or a cable access kit push rod) or even a long zip tie to fish it through the tube.
- Add lubricant: Applying a little electrical lubricant to the grommet can make the passage much smoother and prevent you from fighting against the rubber.
- Use tape: If you have a bulky connector, wrap a small amount of insulation tape around it to help it slide through internal baffles.
Tucking trim and headliner without damage
When you are tucking the wire into the headliner, there is a specific trick to keep things looking neat. You must tuck the cable above the cardboard backing of the headliner, not under the fabric itself. If you tuck it under the fabric, the headliner can sag over time.
Use plastic pry tools to work along moldings and rubber seals. This prevents you from scratching your dashboard or tearing the interior materials.
Be prepared for a bit of frustration when reattaching A-pillar trim. The fasteners (the little clips that hold the plastic in place) are notoriously finicky and often fall down into the footwell during reinstallation.
Dash access for the front connection
To get a clean connection behind the dashboard for your front camera, you may need to move the glovebox.
A common way to do this is with a “one-hand spring-shock” technique. You unclip the spring shock on one side of the glovebox, then press the sides of the box inward. This allows the stoppers to clear the dash panel so the whole unit pops right out.
Model-specific limits and caveats
While these steps work for most sedans, SUVs, and hatchbacks, every car is different. The way a trim clip behaves or how a grommet is shaped varies wildly between a Ford, a Toyota, or a BMW.
Always consult your owner’s manual before you start prying any panels. If your manual doesn’t provide guidance on removing specific trim pieces, you may want to search for a video specific to your exact year, make, and model to avoid breaking expensive interior components.
FAQ
How long a cable do I need? Measure your exact planned path from the front camera to the rear camera, including every loop and turn around pillars and grommets. The stock 6 m cable often runs short on longer vehicles or winding routes, so a longer cable gives you margin.
Headliner route or lower interior route? The headliner and weather-strip route is quickest and easy to undo, since you just peel back the rubber seal and press it shut again. The lower route under the carpet and behind the kick panels takes more work but is widely seen as safer because it avoids the side-airbag zones.
How do I stay safe around the A-pillar airbag? Never run the cable across the face of the pillar where an airbag would deploy; route it behind the airbag module along the edge of the trim, following the factory wiring. Do not fully remove the pillar cover unless you are experienced, because the clips break easily — pry it just enough to tuck the cable behind.
How do I get the cable through a tight hatch grommet? Tape the cable to something rigid such as a coat hanger, fishing wire, or a push rod and fish it through. A little electrical lubricant on the grommet helps, and wrapping insulation tape around a bulky connector helps it slide past internal baffles.
