As title states, I’m looking for the pin locations for the 2-pin plug, used to check the CEL on OBD1 Honda vehicles. A buddy of mine had a swap done at a mediocre shop, before bring it to me. they did a HORRIBLE job on the wiring part of the swap. There are literally wires hanging everywhere. Long story short, he has an intermittent CEL, with no way to check it, because of the shotty wiring clusterfuck i have in front of me. Can someone please help? i have the pinout from FFsquad Tech net, i just need to know which locations are the ones i need to jump in order to check his CEL. :think:
Thanks

It’s to late for me now but if you still haven’t figured it out by the morning I’ll post what to do. Currently doing an obd0 to obd1 jumper install now so I have it all in a notebook in my car.
Yes, please. I have the Helms manual, but have been looking to no avail. That would be great! You can just email me at patric.sanders@gmail.com if you’d like.
Thanks,

If it has the jumper harness there should be a plug that would go for the vtec controller or something like that its about 1in or so long and skinny if the wires are the colored ones on that I believe it should be the yellow wire and the black one. That’s how it is on my jump those two together and it produces the code on the cel.
No Jumper harness
The mediocre shop I mentioned in the first post did not use a jumper harness. Simply repinned the OEM chassis harness from OBD0 to OBD1. They left a nice surprise for anyone trying to fix what they were too stupid to figure out. I’ve already had to rewire his headlights, sunroof, and a few other things.
Anyway, the wiring is nothing short of a disaster.
D4 on the obd1 plus should be the Service Check Signal. All you have to do is connect that to a ground I believe and it will cause the check engine light to flash and you just count the blinks to get the code. Assuming you already know that lol Alot of people run that wire to a toggle switch of some sort so when ever they get check engine they can just flip it and not worrying about having to find something to jump it with.
So just ground D4 to ground and it will flash the MIL?
BTW, the switch is a great idea, you just gave me a great idea.
In theory I think just grounding it will get it to flash yes but I haven’t got around to testing it myself. Still working I. The jumper build myself.
I think Im going to go out and get me a toggle switch now!
