anyone that has done an OBD 1 conversion
i am working on doing this to my 96 and i need the pinouts that show where each wire goes i have akll the other stuff so if you guys could give me some advice that would be great.
Re: anyone that has done an OBD 1 conversion
Resistors can be soldered into the PCM so it can work with the OBD2 knock sensor. This is what I did, all i have to do to go back to obd2 is unplug the computer and plug the other one in. I dont remeber what pins i had to solder, do a search and it should come up.

Re: anyone that has done an OBD 1 conversion
If you are trying to get the pinouts for the connectors, it sounds like you are trying to do something you don't need to do. I have a 96 OBDI conversion and my car is like jchevy's... my OBDI PCM has been modified via a resistor to accept the OBDII knock sensor. If I want to switch between the OBDI and OBDII PCMs all I have to do is unplug one and plug in the other... nothing else.
Re: anyone that has done an OBD 1 conversion
Sensor itself reads a different resistance so resistors need to be soldered in to convert it to what the PCM is looking for. Do a search and info will come up on what you need to do.

here you go just follow this i did it its no big thing.

shoebox is the man. I could not have done the lt1-s10 swap without him.

The PCM that i have has no Knock Module in it so if i swap the knock mudule from the OBD2 PCM to the OBD1 which i am putting in. will that be fine?
i have already soldered in the resistor. so i think thats all that i need is just the knock module

I have used an OBDII knock module (LT4) in my OBDI PCM with no problems as have several others.
