Reverse gear switch connector is right on top of the transmission, pretty easy to get to. I have a 99 wiring diagram, your year may vary. on the 99, reverse lights wire is blue. It goes through several connects on its way from the engine compartment to the taillights. You can tap it in the trunk where there's no question. That is farther away from the radio, but still easy enough.
