I have an OBD0-OBD1 conversion. I got some help in the past on this but it didn't work out for me. How do I wire up the harness on the ECU to make my check engine light flash codes?

 

Bump....

OK, here is my last topic on this: https://honda-tech.com/zerothread?id=466230

Here is the pic I am looking at, its the wire numbered 8:


The jumper wire is coming from the "D" plug on the ECU harness. Can anyone tell me what pin this is. My colors are not the same. I got my OBD1 ECU plugs from a JDM H22 ECU.

 

I just made the same nonOBD-OBD1 jumper for my friend (jdmDXrex) about 2 months ago... As long as you have the OBD1 point (A13) running to the nonOBD (B6) your CEL is connected to the ECU... Now in order to activate it you need to simply ground the wire running out of your OBD1 point D4... Just looking at your harness I would recommend soldering all your connections instead of those red crimp connectors... Just my $0.02 Latez

EDIT: My bad I didn't really see your little part at the bottom... If that's what you're pointing to (looks like a yel/wht wire) just ground it... It should be D4... Is it coming out of the bottom row, second pin in from the outside?? If so, that is it... As you can see on my friend's jumper I made it the long orange one... Also from the pic I can see that you have your VTM signal labeled (8), KS labeled (7), but where does your D5 pinout trace (wht/blk wire labeled 6, well either that or 9)
