Ok so i started to swap the Manual 89+ harness into my 1989+ supra. But i noticed that there are 4 other clips that hook up somewhere to some wiring that comes out of the upper dash. The problem is that out of those 4 clips the white clip is bigger on the manual harness and on the other 3 clips the pins don't match up with the wiring that comes from the dash. (pretty hard to explain and i don't have a camera)
What do these four wiring clips go to??? And also I thought it was just plug N play like i was told on here???
Both wiring harness have the gray ECU plugs.
My original ideas was to swap out the auto ECU and harness for a Manual Harness and ECU. Im doing this because i couldn't find an auto harness that was in good conditions to replace my current one, since the one currently on the car is all messed up. So i found a manual harness and manual ECU in very good conditions for a good price and i decided to swap them, but now i ran into this problem
