I need to know where the plugs go from an OBD1 dizzy to an OBD0 ecu.



Those are for the pinout for OBD1 ecu, I need the same but OBD0. If anyone knows and could help me out please post. I tried searching but I only found full OBD1 conversion stuff not just obd1 dizzy on obd0 ecu.

Thanks.

 

Can anyone verify that that's how it's suppose to be? I think it's right. I'm looking at it the same way the above picture is.

 

EDITED FOR Units

It won't work. Sorry guys, the OBD-1 Distributor sends out a different amount of pulses than the OBD-0 ECU. OBD-1 = 24(signals / rpm), OBD-0 = 16 (signals / rpm)

Which signal is off? I ran the car and drove it around. But throws a code.

When I converted my rex, All the colors from the dizzy are the same. did you get the plug in that picture with any wires on it? If you did then you made the mistake of taking them out (one becuase the colors match up, two because I don't think the obd0 dizzy pins fit in the newer obd harnesses)...at least I think.

edit..ok so yea you can't run an obd1 dizzy with obd0, they need to be ecu specific. so unless you have an obd1 ecu then you can

 

If you like, I have a B16 obd0 dizzy and we can just trade...I have no use for it since I already upgraded to obd1.

I got the DL on what's different between OBD0 dizzy and the rest.

Crank sensor pulley has 16 teeth inside the dizzy for that sensor in OBD0, OBD1 and up had 24 teeth. Explain my code 4.

I'll know tomorrow to confirm if it fixes my issue. I bought an OBD0 LS dizzy (the engine I'm running until I scrap this car for 40$.

 

And I should post that the above diagram is correct. Unfortunatly there is no point in running those plugs, unless you want to run nicer looking OBD1 or OBD2 plugs (same diagram for both).
