im looking for a mint wiring harness from ecu to the motor for my 86 22re and have a guy that has one from a 90. are the only differences between the two the style of injector/injector plug or are there more things? and what would those things be?

 

bro why dont you buy a original harness from toyota of dallas it will save you 20 asprins ... im damm good at wiring and my rule is follow the diagram and you will hav no headaches and we all know the pain and hours it takes to find and fix em !!

 

the early and late 22re harness are alot differnt. does the 86 one u have have 5 plugs?

 

how much is a new wiring harness from a dealership?

 

The 90 and 86 harnesses are completely different. They will not interchange. You won't just be changing a few plugs, you will be hacking the harness to bits.

Can you not use the harness that originally came with your truck?

 

i COULD reuse the harness, but some of the plugs are damaged and dont click lock in nice and there are already some repairs that have been made to it. i just want to peace of mind that all the connections will stay hooked up, and it wouldnt hurt to replace the 23 year old harness....IF they still make them

 

I say get replacement plugs, solder all connections / splices, heat shrink things and call it good. That'd probably be better than the factory harness that has crimped splices and things in really bad places.

 

You can just replace the connector. First you have to figure out what keys the individuale wire in the moulding. If you go the the junk yard and cut one out you should be able to cut it up and figure it out. Then find good connectors, pull the wires and swap into yours. Revisit the previous repairs and make sure they are up to snuff. A little work but way cheap. The metal connectors will have some kind of clip that you will neeg to depress to get the wire out. Could be that a little piece of metal tubing will slide over the connector and do it. Haven't looked at that style connector but i'm sure it can be done.
