I’ve got a 91 GS with a missing distributor. The only spare I have is off of a 92 GS. Aside from the connectors being different, is there an actual difference in the distributors? I noticed most of the wires were the same color, aside from two of them. The 91 had two white wires, the 92 has only one white wire, and a thicker wire of some color that doesn’t match with anything on the 91.
If there is a difference, would I be able to use the obd1 with the obd1 ECU? Are the ECU connectors the same on both?
Not sure but you can get a new one with a life time waranty from www.autozone.com for 109.00 bucks. Thats the cheepest I found and it comes with a new (mine did) coil and ignitor…
internally they are different. your car is obd0, you need an obd0 dist. you could repin the obd1 distributor and plug it in…but your ecu won’t know what to do with it. sell the obd1 dist, and buy a used or new obd0 dist. typically the obd1’s are a little more costly, so you’ll at least break even and probably make a couple bucks.

With the obd1 distributor repinned for it, will a obd1 ECU work? Are the connectors the same for the ECU? [/B]
I am unaware of the exact differences, but i know they are there.
no, the obd1 ecu will NOT work if you repin the obd1 dist. The differences between obd0 and obd1 are much more complex than just a couple wires on the distributor.
remember how your obd1 dist doesn’t even plug into the obd0 harness? well, same with the ecu. the plugs for obd0 and obd1 electronics are just different. If you’re really set on going obd1 then buy an obd0 to obd1 jumper harness, but thats pretty stupid way to get around having to buy an obd0 dist because you’ll end up spending more $$ and the extra time doing wiring and rounding up parts.
dude, i was in the same predicament a while back. the difference is actually inside the dist. the three sensors inside it tell your ecu vital info. there are three little “wheels” on the shaft inside, with different numbers of teeth on each. when each tooth passes the magnetic pickup, it sends a signal to your ecu. on OBD1 dist. there is a larger number of teeth on the crank angle sensor “wheel” which, even if wired to the ecu correctly, will give a false reading to ecu. this happened to me, the ecu thinks the engine is spinning faster than it actually is, and will redline it at 4000 or whatever it thinks it is at. to make a long story short, get the correct dist. for your ride=no problems.
i have my old non OBD dist if you are interested.

Thank you, this was the answer I was looking for. Unfortunately, I was under the impression they were the same, and just had different plugs. Thus I already cut the plugs off of the engine harness and put obd1 plugs on. So was last question is, are the casings the same between both distributors? Could I move the internals from an obd0 over to an obd1?

cut plug=sucks, just re-connect your original plug. yes the housings are the same, but you cannot get all the wheels off of the shaft-i tried. so, no the internals are not interchangeable. only thing to do is get another non OBD dist.
Well, he decided to go OBD1 (this is my friends car that I am working on) so that he can use my hondata ECU in the future. He is getting the OBD1 connectors for the ECU tomorrow. Does anyone know if a site with the wiring diagrams for the obd0 connectors. I have a helms for my 92, so I know where everything goes on the new connectors.
