I am working on swapping my 3sge T18 with a 3sgte from a MR2.
I noticed that with the 3sge harness, the fusebox comes with the engine harness and with the MR2 it has plugs that plug in to another piece inside the car. (What the T18 hasn't)
Is there any way (To do for me as mechanic) to make the harness fit on the Celica? Or is buying an ST185 harness the way to go for me?
