In case anyone is interested (and as a reminder to myself of what I did
), here is how I installed a wireless rear view camera in a 2016 ProMaster (Winnebago Travato).
1. The harness for the mirror/monitor runs inside the headliner, down the A pillar, and then drops down through the dash from the right bottom point of the windshield. It helps to remove the upper glove box (open the lid, take out four screws, it lifts out, and it's a bit easier to reach in and guide the wires down; then they can be retrieved from under the dash.
2. The wireless receiver is mounted on the passenger side, on the right side of the dashboard. It fits, even with the door closed, and is space otherwise not used.
3. The power wires from the wireless receiver run under the dash and tap into the 12 volt cigarette lighter (powered when ignition is on or engine running). Thanks to proEddie for the hat tip on this part.
4. The camera is a side mount but when it arrived it was clear that the camera would not cover the hold in the side panel so I opted instead to mount it on the right side of the trailer hitch. (For what I want it for, to see when I'm past someone in the lane to the right of me so I can change back into that lane, it works well enough).
5. The wireless transmitter is mounted on top of the trailer hitch.
6. The power wires from the wireless receiver tap into the 4-wire trailer electric connector. I used the ground and the "park" feed (which is parking lights). The camera is on only if the lights are on, which might not suit everyone but it works for me because I always have my lights on when I'm driving (as Winnebago did not order a Promaster with the daytime running lights option).
It took me about 5 hours, but (1) I'm slow, (2) there was a learning curve, (3) I changed my mind about where the camera would be, (4) the quick-splice connectors aren't so quick, and (5) I did a lot of experimenting as to where to run the harness for the mirror-monitor. So folks who are handier probably can do this in less time.
[If this belongs in some other forum I apologize, and moderators, just let me know if you move it. Thanks.]
