Hi all,

i want to know how to wire an 2 Wire IACV into an OBD2B harnass.

the OBD2B comes with an 3 wire iacv but i need to convert to 2 wire for my obd1 ecu to control it, now i have got an intake manifold with an 2 wire sensor and pigtail.

which wires do i need to use ??

Thanks for your help

 

YEL/BLK = power source (+)
And the second wire (ECU grounded) needs to end up @ Pin A9 on the OBD1 ECU.

Not 100% on the wire colour or it's OBD2B ECU pin location. Sorry!

Are you using an OBD2B to OBD1 conversion harness?

 

yes i am using an obd2B to obd1 conversion harnass

 

You should ask the manufacturer if they made any pin/wire changes for the 3 wire to 2 wire IACV.

 

The conversion harnass had the conversion in so i just wired the new plug on the old cable and the car is running very nice.....

Thanks for all your help guys
