IAC connector?

Call your local dealer and see if they sell a splice kit for that connector. Junk yards are usually unwilling to part with bits of a harness unless most of it was crisped in a fire. If the connector still looks like mine (and I suspect it does) then you could find one from any one the Jeep 4.0 engines.

GM also used a lot of those connectors - try one of the local GM dealers if Chrysler doesn't work out. If you can get the shell, the pins from the old one will slip right in - but you'll probably have to destroy the old on to get them out. Without the (expensive) removal tool, they are a bear to pull out.

Flat style connector pins can usually be pulled by a home made tool from a hunk of piano wire. Whack the heck out of the wire on an anvil or similar hard surface [e.g. brother in laws head] and then file and polish it down to a nice flat area a couple inches long you can poke in to release the little latch on the side.

The round ones are harder, but you can make a removal tool from a hunk of hobby steel tubing.

Or just buy a couple of the commercial connector removal tools from an online electrical supply shop.

I've got a set of tools I made a long time ago.

You just need a nice strong beercan as donor metal. Cut a small patch out (about 1/4" by 1") and roll it around a bit of coathanger wire, then cut off the extra so you get a C shape. Sometimes you can use a scratch awl as the form.
