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 )
