Hi all,
'98 Silverado with factory tow package. Wiring up a 7/4 pin Hopkins receptacle. Very straight forward, uses a T to splice into the factory 4 pin taillight harness, and then separate wires for the +12v, brake controller, reverse lights and ground.
The harness coming back on the driver's side frame rail has:
Blue: terminates under hood, will connect to brake controller
Orange: terminates under hood, will go to 30A 12v aux post
Light green, dark green, brown and yellow: go to 4 pin taillight harness connector.
White wire: I assumed this was ground. I wired only the 4 pin side up for now and tested the lights. As soon as I hit the brake it blows the STOP/HAZ fuse and I lose everything. Is the white wire actually for the reverse lights? When I disconnected it from ground everything worked as it should, but I can't seem to get a positive voltage indication on it when the truck is in reverse. I followed it up to the engine bay but can't find where it terminates.
Thanks!!
