Icon2 How to wire an 2 wire iacv

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?

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