Has anybody hooked up a 4 pin trailer light harness to a 1st gen 4runner?If so how is it done since the lights are all on different circuits?Is there an adapter-I've checked a couple of places with no luck.Any help is needed so I can wire this myself.Thanks

 

My son bought a kit at NAPA. It plugged into the harness of the truck (behind each tail light), connect a ground wire and done. There was no cutting of the factory harness. His is a 85 pickup, should be the same as your connectors.

It has the adapter built into the harness. It was something like $50 USD.

 

Thanks,I never did try Napa i guess it's the next stop.

 

all you need is a diode box to seperate the turn signal. I got mine from draw-tite

 

the napa deal is really easy, and has the diode thing.

 

To make the truck connection work on a 4Runner will require a bit of drilling, cutting & splicing. On the trucks, the back of the taillight is exposed, on the 4Runner it is enclosed inside sheet metal. You will need to drill a couple holes for the wires and then cut off the connectors, feed the wires through the holes and splice them back together. This is what I had to do for my '85.
