Right now I'm in the process of doing one of these harness conversions from scratch.
Here are my tips for anyone that wants to do this:

1. DONT DO THIS IF YOU NEVER DID ANY CAR WIRING BEFORE. If you dont know how to solder, or use heat shrink tubing or read wiring diagrams and dont have a clear understanding of how automotive electrical systems work DO NOT DO THIS.

2. Follow batmans advice and buy the toyota wiring books. Why? Well we do have a few engine wiring diagrams floating around on the net in PDF format. They will give you about 80% of the info you need, however there are certain specific functions that are not part of that engine wiring diagram that need to be looked up in the rest of the book.

3. Make sure you have plenty of free time. While it might take someone whos done this before a week or so to finish, the very first time takes the longest because of the amount of research and note taking that you have to do to figure out what wire goes where.


One of my original goals during this harness project was to document everything and to post a giant how to. However after putting in all of this time and effort, I can see why the people who currently do this service, do not just give this kind of information away for free. It takes an very long time to research each part of the two cars electrical system and figure out how to mate them together. Not to mention that I would also hate to see people who have never done any major wiring before try to follow any kind of tutorial and burn their car to the ground.

Having said all that, if your into wiring, buy the books, make your notes and go for it. Its actually a really fun project.
However if you are just trying to finish your swap and get your car running, go mail out your harness to someone like DrTweak. The 400bucks he charges is a bargain for the amount of time and effort it would take you to do this on your own for the very first time.
