Re: RS Rear Wiring Harness
Electrically, the 68 and 69 are the same, but the bulb sockets are different. The 67 and 68's ground through the tail light housing. The 69's have a seperate ground wire that splices all tail lights together and grounds them at the truck lock support. Plus, according to the factory electrical diagrams, the 68 harness connects to the main dash harness near the fuse panel. The 69 tail light harness connects to the mid body harness above the left rear wheel well. The mid body harness then connects to the dash harness like the 67 and 68.
You could make it work with new sockets, run your own ground wires, and extend the wires all the way the the dash harness, but the aftermarket sockets that I have tried at the auto parts stores really suck. They don't stay secured in the housings very well. A lot of work, but possible.
