READ CAREFULLY: The procedure to add IABs is different depending on how they are wired. One IAB wire will always run to the ECU, the other will run to either +12v or gnd. Choose the procedure to match how your car is wired! This is very important!

USDM ODB1 B18C: ( ECU sends ground, IAB wired to +12v )

IAB conversion... (this is for Manual cars only, but an AUTO USDM ECU converted to manual will have all the parts you need present)

Remove: R135...11F0/1720 autos only R150...1980/LS only

Add:

Jumper wire for OBD1 IAB control:


I am trying to make the iab work with my p28. I have already soldered the jumper wire in from r135 to d13. These directions are just confusing me ? Does anybody know how to do this? Thanks
