Ever wanted to build your own harness?
 

Been doing lots of research... figured I'd make a diagram for anyone who wants it.

This is all you need to make a 2j harness for ANY car.

Very cool!

Wow. Good info

Thats awesome also for anyone that is trying to track down a problem as well! nice!

I don't understand how this is any different/better than factory ewd. Factory is more clear, gives fused values, has complete flow chart and is applicable to any universal application as long as you assign an output of your vehicle to its corresponding circuit on your new engine harness. I made gfs 1jz sc harness from scratch using mk4 ewd and aristo pinout , my daily I did the same thing. Vvti 1j into Cressida using vvti 1jz pinout and my sportcross ewd, and am currently doing the same for a vvti 1j into my sc400. IS ewd, vvti 1j pinout, sc ewd.

Edit: A few weeks back I actually made a harness for aristo into a mid 70s 280z from scraps I had laying around using only 95 mk4 tsrm. Car fired right up my friend couldn't believe how it runs so well.

Basically what I'm getting at is that this is primarily the easy part and most people already have a harness to start with and if they dont and are undertaking this, they probably have an understanding of what needs to be done. What most people will probably have trouble with is figuring out how to mesh the Toyota stuff into the universal app by adding relays and fuses and such. Depending on new chassis, there's a gazillion ways to go about this.
