Hi; What is the easiest way to get an accessory small cable from the front inside to the engine compartment. I need to add a front sensor warning kit to keep me from getting too close to obstacles like packed cars or my closed garage door. I have a detached retina situation going on and my distance measurements are pretty screwed up for now. Thanks, Don
You can just piggy-back off of your DRL or find a feed that activates when the car turns on - your under hood fuse panel.
I need to get the sensor cables (2 very small wires) into the cabin area under the dash where the main unit and buzzer are located. If I can’t find a way through the firewall I’ll have to extend the cables and get them under the car and then up to the dash area. Thanks for your idea. Don
I don't know gen 4 specifically, but the rubber grommets that seal the firewall holes where the factory wire harnesses pass through usually include one or even two small nipples molded into the rubber, allowing you to poke a hole and run additional wires through.
Your profile says you've got a 2015, which I believe to be part of the Gen 3 line. There are a few threads on adding fog lights to a Gen 3 where it comes across as a factory install instead of a hack job. Those instructions include running another wire through the firewall. I think you could do the same thing.
