How's it going YotaTech! Finishing up an EFI swap and I'm working on the harness for the tail lights, hazards, blinkers, and brake lights. The donor harness was from an 86 4 runner with the 22re. The truck that the harness was swapped into is an 87 pickup that originally had the 22r. The donor harness doesn't not reach the original pickup harness located under the passenger seat, and the pin out is different.

The 87 pickup has a flatbed with different lights being used instead of the stock lights. I'm not sure how correct the wiring was, but everything was working with the original harness plugged in. I'm having some trouble getting the correct wires spliced together. I'm not the best with wiring diagrams but I've managed to figure out a few of the wires. It would be greatly appreciated if someone could number the pin and what that wire goes to on both the 86 4 runner plug, and the plug for the 87 pickup. I'll post some pictures and hope it helps with getting my issue figured out.
