Noob here , just bought a 1989 Tacoma 4x4 with 22R engine. The PO has butchered the underhood wiring ; I have the Toyo manuals from 1990 ; are the 89 and 90 Toyo's wiring the same or similar ? I think a new underhood/engine harness might be a good start . Thanks for the thread on starter re and re . Looks like fun with IFS. Be safe...Bob.
