April 4, 201510 yr Hey all. I did try searching i just didnt find anything. I'm in the middle of swapping in a ej22 into my gl. The harness is from a 92 and the engine is a 90. The engine harness has three grey plugs while my harness has two white / grey plugs. Can I just switch the engine harness? Thanks
April 4, 201510 yr Yes you need a 92 intake harness. And if the Intake is from a manual 90 car, you will need a 92-94 iac also.
April 8, 201510 yr The third plug is almost all grounds on the early harness if that helpsit's all grounds. But the wires int the other 2 connectors have a completely fDifferent arrangement. 1 wire of 1 of them is in the same spot Get a correct intake harness
