It's not part of the cruise control unless GM changed the wiring in the newer trucks. My 83 cruise should go back to the late 70's. I'm not sure on the A/C. The compressor should have a different connection unless the older compressors used a different type. Where does the wire lead from? Is it live? How many volts going through it? Looks more like a washer bottle connection.

It looks like it may have gone into the stock carburator.

My 83 had a computer of some sort in the pass floor panel or maybe in the dash. I took it all out. Trace it down and cut it out. You wont need it with a carb that you are runnning.

Btw the way the nipple left over had a hose on it that went to the carb to sense WOT. MAP stands for M______ A- absolute P-pressue. Forgot what M is sorry!!!

The thing the yellow arrow is pointing to is not a MAP sensor. It's the low vac switch for converter lockup.

If your tranny is a TH350C, yes, it's needed in order for the converter to lockup. If it's just the plain TH350, then no, it's not needed.
