I have built a formula four style buggy but am very electrical illiterate.I need help locating a site or info on how to delete all the extra wires from a 91 pickup wiring harness to make engine run . Any help will be greatly appreciated
The ECU is going to need all the engine sensors to run the engine correctly. If you get a manual you should be able to figure out what wires are needed. You can cut everything except the bat pos, key power, check eng light, starter, etc.
If you are totally lost we can cut your harness down for you. Give us a call.
The haynes won't do it? I haven't looked in a while, but it seemed like they used to have a pretty complete wiring diagram section....or else there are always the service manual links in the toyota FAQ.
