JDM P72 Help!
Does anyone know for sure if an OBD-1 JDM P72 ECU sends a ground signal for the IAB's liek the USDM ecu, or a +12V signal like the OBD-2 ecu's? I keep reading mixed info when I search. Thanks
depends on the year of the P72. some were 12V active, some were ground active. I've seen both, yes it's a minor headache. I've never really dug into what years are what, or what versions are what. It's easy to tell what's what once it's plugged into a car.
this is my $0.02, keep in mind that I can't spell
