Long story short. I bought a 5sfe wiring harness for a 92 celica automatic because it had all the right plugs (and it was dirt cheap at $40). I'm going to be converting it over to run my 3sgte from my mspnp2.
The ecu side of things is pretty easy. Yes I know the 5sfe is setup for batch fire injectors but I'll take care of that.
The problem I'm having is what are the other 2 plugs called that plug in to another wiring harness next to the ecu. I'm assuming its things like tach signal, cruise control, etc. I have the ewd book but I'm not familiar with what I should be looking for, for pinouts.
Reason I'm building a new harness is I've eliminated a lot of things on the car, like egr, ac idle up valve, cruise control, AFM, injector and fp resistors, and I'm going COP wasted spark. I want a fresh start instead of hacking up my original harness if I ever revert back to stock.
I'm just looking for a basic pin out for the 2 connectors so I can move wires around or remove if not needed.
