I know, search function, look it up, etc.
I cannot find what I need anywhere.
I need the connector pinout for a 99 xj iac valve, I am retrofitting a stock manifold and throttle body from a 99 to my MegaSquirt controlled renix era cherokee, and I found the tps pinout, but I'll also have to have the throttle control and it wouldn't be terrible if someone knew the pins for the MAP sensor as well, although I have an onboard MAP on the MegaSquirt.

Thanks! Weird that they're all listed as drivers, no 5v, 12v, ground, etc.

That's because it's a stepper motor. Any of those pins may carry power depending on how the PCM is operating it.

I wired my renix era stepper in to my mega squirt, and I definitely don't remember 4 drivers, seemed like one or two IIRC. I just moved the old stepper to the new throttle, we'll see if it works, bolted right up, pintle shape and length appear identical.
