i searched and searched, some people say you wire it up to A17 and others say A26, which one is correct?

who have actually wired this up before?

THANKS

 

i'm positive it's A17, who the hell say it's A26?

 

For an OBD1 ECU, the PNK/BLU wire on the IAB sensor plug will go to A17, the YEL/BLK needs a 12V+ source. Due to it's location it's easiest to tap into any YEL/BLK wire for the injectors or the IACV.

I thought only one wire needs to be hooked up to the ecu, and the other to a ground?

OBD1 P72 ECU's use a 12V+ trigger for the IAB. The YEL/BLK wire connects to the 12V+ wires that go to A25 and B1 (Power Inputs) then the PNK/BLU goes to A17. The OBD2 P72 ECU's use a 12V- ground trigger.
