This involves the wiring for the parking sensors.I may have missed it, but I'm unsure what you are installing. It would make a difference on my advice on routing. I have wires routed along the driver's side trim panels/door sill plates/headliner and others routed under the center console/under the carpet/under the cargo floor and exiting through the rear hatches accordion boot to an external antenna .
I have to run the wires from under the driver's steering wheel to the front and rear bumpers.
I think I know where to route the front ones, and for the rear ones, I was going to run them through the lower door frames, next to the carpet, by removing the plastic panels all the way to the trunk—where the jack is used to lift the car—but from there, I don’t know how to route them to the inside of the rear bumper.
