Hello, so long story short I got a 97 automatic 3.4 in my 3.0 91 Toyota pickup 4x4 and all I have left is to wire the car. I got the wiring harness diagrams but I'm having a hard time understanding how to adapt it to the body harness and where the e9 plug needs to be spliced into. If anyone has any good resources I'd really appreciate it

 

Subbed. I’m debating about swapping..

Pay special attention to 3.4 swap wiring theory by the Monch. Or buy a conversion harness.

 

i did my own harness, if you ahve the drawings for your car and the ECU you plan on using its really easy. Toyota color codes all the wires. What I did in my swap is use 90% of the 3.4 harness and added in the few wires and plugs from the 3.0 I needed.

 

I understand the basic requirements was just wondering is the part that needs messed with is gages and stuff if thats the case after market games are super easy

 

The part that's difficult is adapting body harness wires to all of that. I have a right up on my fourm on it. Just get TIs if you got any questions feel free to message me. (I'm an electrician for a living)
