Hey all,
I've gone through many, many posts of exactly the same kind of question. I've read a million versions of the OBD0 and OBD1 pinouts. The problem I've had is that the pinouts that I've seen and the pinouts documented by Honda in the Helms manual DO NOT AGREE. So, I'm frustrated beyond belief. I even thought I solve it all by buying a OBD0 to OBD1 ECU jumper from Katman. Unfortunately the jumper puts things into the p61 ECU where it doesn't have any LISTED functionality. It also tries to take things from the 91 CRX wire harness that aren't supposed to even be there. As a result, I'm completely confused.
What I really need is a list of what existing signals need to go from the 91 CRX wiring harness to which pins of the p61 ECU. Then I need to know which signals need NOT to go from the CRX wiring harness to the p61 ECU. Then I need to know which signals and sensors I need to add to the CRX wiring harness and which pins on the ECU they need to go to. All of this stuff needs to use the same pinout strategy (ie either the z pinout of the integra ECU connectors or the horizontal pinout listed for the harness connectors) for both the CRX Si stuff and the integra p61 stuff.
Please where do I get help for this?
