Thanks is advance for your help. I have a 94 NA-T. I manage to completely break the plastic part that hold the wires together that plugs into the IAC. Unfortuanately, a friend was helping me and he moved the whole thing out of the way and subsequently got the wires all out of order (now there are loose wires that are not in the connector. I have been trying different patterns and plugging them individually into the IAC, but there are so many wires I don't think I'll ever get the right pattern w/o some help. I can't seem to find the IAC wire harness diagram in the TSRM either. This is my biggest problem. If anyone could take a picture of theirs and let me know the order of the colors that would be awesome!

Also, after changing the head gasket and putting the head back on I can't figure where 2 other harnesses go on the intake side (Have the plastic harness but can't find where to plug them into the head/block). My oil light comes on and my temp guage doesn't move at all (always shows all the way cold after warming up). I am assuming these phenomena account for the 2 harnesses unplugged... I have checked the TSRM for this too but it doesn't really have a good diagram that I can make sense of. Any help is much appreciated!!

Best regards,
Robbie

Thanks DrNick!

I can’t seem to find the information that I need from the TSRM, though. I followed the link and checked out all of the sections about wiring. There is a diagram of the IAC wires on p. 267 of the electrical diagrams section, but it doesn’t say the order of the wires as the plug into the IAC (or if it does I cannot understand it). I am just going to plug them individually directly into the IAC because the plastic clip/harness that holds them together broke. There are 6 wires total in 2 rows of 3 (if you are looking at the front of the engine bay). Could you or someone take a look at your car and let me know the order of the color/stripe of the wires. The colors I have (and verified in the TSRM) are: R-G (red w/green stripe), G-W, G-O, V-Y, and 2 B-R for 6 wires total. Please let me know the order of the front row from top to bottom and the order of the back row from top to bottom. Here are some pictures of what I am talking about. I really appreciate it!!!!!!!

I hope this isn't too late , but if you unplug the connector and look at it straight on, here are the wires.

From left to right

Row 1/Top side closest to the locking tab : Green/White Stripe - Black/Red Stripe - Red/Green Stripe
Row 2/Bottom : Purple/Yellow Stripe - Black/Red Stripe Again (may be a little bit thinner than the one in the top row) - Green/Orange Stripe
