88HatchMonster Posted May 11, 2006 Share Posted May 11, 2006 Wish I had some great advice for you... When I did my wiring I ran 4 or 5 ground wires from all the points that needed to be grounded off the ECU and harness straight to the negative battery terminal. In other words I didn't really trust that they were getting to ground through the harness. There were two wires that were vaguely labeled in the Chiltons diagram, I traced them to the ignition switch in the donor car. I believe one was powered up in ACC, the other in start. I wired those in directly to the EA81 ignition switch. Are you using a Chilton's manual for the wiring diagram? They aren't great, but they will get you there. I can upload a copy of it and post a link for you if you still need it. Don't lose heart, it really doesn't take much to get these engines going, whatever it is you'll figure it out. Just start going back over it, wire by wire (not fun I know, but you'll get it). There is literally nothing like hearing your EJ beast fire up for the first time!

Matty B Posted May 11, 2006 Share Posted May 11, 2006 There is literally nothing like hearing your EJ beast fire up for the first time! That is the gospel truth. Keep at it. Link to comment Share on other sites More sharing options...
WoodsWagon Posted May 15, 2006 Share Posted May 15, 2006 While working on stripping my EJ harness down, the temptation to chop all the wires 6 inches from the ECU and doing it from scratch was almoast overpowering. It can be soo frustrating tracing out each of the wires. Link to comment Share on other sites More sharing options...
