I cant find anywhere online how to set up the reverse lights for my car. I have the 2 wire clip form the r154 just don't know what 2 wires I need to splice into on the auto harness side. I think it is one of the round plugs that goes to nothing not sure thought. Has anyone done this swap and know what 2 wires on the harness I need to splice into and hook up to the tranny clip?
