Idle control and maybe intake leaks, how to for swapping in a 52mm Vanagon throttle body Options

I broke the plug to my idle control valve. I bought a new plug housing. Easy. But I’ve had a devil of a time finding the right socket pins for the housing. Several weeks have been stalled waiting for 80 cents worth of pins that show up and are the wrong size.

So, knowing the 914 has to drive next weekend, I went full DACO and soldered a pigtail of wires into the ICV and then crimped them into place.

About to find out if it works, and will continue to work for a couple weeks while I sleuth out the right sockets for the plug Wish me luck!

Bought another IAC and found a proper plug and pigtail on ebay. It will come in May, so my cludge will just have to work till then.

I would just plug the line to the IAC, and open the air bypass on the throttle body for now and run without it. Once we get your idle mixture and warmup curve dialed in it wont be as much of an issue (for sure will be better than a cold start with carbs) maybe 20-30 seconds of feathering the throttle to avoid stalling, or possibly even just a low idle during warm up.

I suspect the amount of air this was letting through was masking other issues with your idle quality that should be sorted out before enabling the IAC at all. Your car should be able to idle strong without it.
