I am looking for recommendations and suggestions on wire routing for rear dashcams (Viofo A129 Duo).

The vehicles are 2017 Acura MDX and 2019 Honda Odyssey. I've done front dash cam wiring on much older similar vehicles without issue, but these have more intricate interior panels and more airbags.

Power will likely be hard-wired into the passenger footwell fusebox via the A-pillar. I'm specifically interested in routing of the wiring for the rear camera from those that have done it.

I am leaning toward routing via the passenger side under the door sills and lower interior panels, but I think I've read of some folks on here routing via the headliner and upper door trim. I'm concerned about messing up the headliner (and having to look at it for forever) or obstructing the side curtain air bags with the upper routing.

Once at the rear of the vehicle, I'm planning to bring the wire up to the liftgate hinges and through the existing wire looms to the top of the rear window.

Hi @thebravo. I saw a thread from last fall where you mentioned that you used the upper route for wiring to the rear on the Odyssey. Did you run into any issues? Still recommend it? Thanks in advance!

Hi Coralreefer. I actually have my systems pretty much fully separated front to back at the moment, but that will be changing soon enough once I get my rear ALP heads. I have a rear dashcamera, but it's a separate unit from the front and is powered off the rear accessory port in the rear cargo area. That said In the workings I have done in the car the floor trim is generally the way I would lean myself the panels pop off way easier (if you even need to there is quite a bit of space I can get to just pushing down on the carpet or gently lifting the panels.... around the top the panels are much tighter fitting and a little harder to remove... If you have the length of wire needed i would think this would be the easier way to fully dress the cable front to back, just make sure the cable isn't going to be pinched when folks climb in and out of the car. It is a long run, when I tied a temp ALP head on the rear door I needed every inch of the normal cable, and an extension cable plus what was on the head to just reach on the left side, the right side I would need even more length.... For the rear cash camera I might suggest of you can to mount it to the ceiling trim right under where the power lift gate mechanism is (on the driver side on the 2010), there is a nice flat spot there that you can easily attach to. with some good 3m tape or you can even fish a ziptie around the panel and strap it in. I currently have a redline EX mounted to there via ziptie for some testing, I have the dash camera ziptied onto the center seatbelt retraction point trim in the ceiling.

Thanks @thebravo! That's great info. I hadn't thought of using the ceiling trim in the back. Will definitely look into it.
