so i got the engine today from jdm and i realized the to harness plugs go into the 3sgte ecu just fine but that leaves me with a third plug that doesnt fit from the 5sfe harness. i did some research and i found that there are 13 wires i need to redo but i dont have and cant find the diagrams. my car is a 90 celica gts, the motor from jdm is an st185 but i dont know what year it came out of. im really frustrated. could some one possibly help, do i need that third ecu plug off of the front clip the engine came out of ? im goin out to work on the car now, i'll come back in and check on this forum in a few. thanks

Tons of archived info on this swap in the Forced Induction forum. Also might want to re-ask the question there

Its very simple, you can get that plug from a 90s camry v6 automatic. and truly there are only 3 wires needed to hook up to run it. 3 power wires i believe. look at the 3sgte pinout.
