UPDATE - So it's been a while since I messed with the Jeep. Before I tore into the IAC to clean it, I pulled the connector from the VSS and double-checked what I had done before. I noticed the pins inside the plug were recessed (from the open end) quite a bit and compared it to the distance the pins on the VSS are recessed. It looked as though if they even touched, that they barely did. When had I rewired the plug, I inserted the crimped pins inside the HESCO plug just far enough for them to click and lock (Like I had done with all the weatherpack connectors I used). So I pushed the pins further into the plug from the back, making them barely recessed into the plug when looking from the open end. I inserted the plastic lock/separator into the end and the pins stayed in the new position. I plugged it into the VSS and the thing works great! Apparently, the pins were making contact (since I never got the VSS code) but not enough to work correctly? That's a guess, but it works great now! Problem solved. Thank you to everyone for your help with this!! Now that I figured it out, it's a little embarrasing it was something so easy. So if anyone else is planning to use the HESCO plug, push the crimped pins as far as you can into the plug. They'll lock there..
