I am looking for a complete 1985 wire harness either out of a 2wdEFI or 4wdEFI Toyota to install into my 85Runner. I try putting an 87 harness and it's not working properly, every time I floor the gas pedal, the CHECK ENGINE light shows up and stay on. I talk to a few mechanic and they suggest I use the proper year wire harness to correct my problem.
