Question about IAC Wiring

Post by cj91legss »

So ran some new shielded wire to the IAC today, but I only replaced the Open and Closed Wires (Black & white) on the outside pins. I'd love to replace the Middle Yellow/Red wire as well, but wanted to know where it splices into the ignition relay. Based off this Diagram I don't see where the IAC gets it's ignition power from

So does anyone know where exactly in the Loom the Yellow/Red wire gets it's connection?

You need the page that shows the IAC.

Most likely it's a splice on the intake manifold harness as the coil and other devices may also need that power.

Yeah, it ties into the same power source as for the ignition coil, canister purge solenoid, & ignitor.
