Okay so I'm swapping an OBD2b gsr into my 91 Civic wagon, the car is converted to obd1 and im running a p28 ecu. my question is does anybody know where i can get a wiring diagram or a Tutorial on how to wire an obd2 dizzy into my obd0 harness? I do its not just matching colors the colors are not the same... I know its possible because rywire sells a conversion harness i just dont want to spend the money on it.

 

i sell them too. lol

 

Lol well i dont want to buy one... Any help? I know somebody knows what to do.

 

I know I do.
