What is this connector?
 

I was cleaning my engine bay today getting all that nasty winter crap off of all my polished parts and found this. What is this connector for?

Should be a mate to it coming off the distributor. Your distributor may have been swapped to the old style which does not have this so, someone left that hanging out.

As far as I know it had the original 85' HEI dizzy, then I had a guy replace it with a MSD HEI couple months back.. I wonder if it connects up to the MSD, I didn't see any other wire though, what's the function?


I should add, the truck originally had a 305, now has a 350

IF your current distributor does not have the mate to that plug coming out of it, a pre computer style distributor was installed. The computer has been bypassed for that part.

Personally, you/your motor are/is better off with what you got now, in my opinion.

It was for the ESC (electronic spark control) module that those trucks came with (plugged into the distributor). It retarded spark advance based on a knock sensor that was on the lower passenger side of the block.

Thanks guys. I knew that connector wasn't there until recently lol

Just kind of scared me seeing an unplugged wire!

GM set up a lot of trucks with both set up's for the DIST.. As my 84 has duel set ups parts truck that I got all the wiring w/fuse box & front clip off for my 77.

That would explain it. Thanks you guys! Today was a good day, I've been having a pretty serious oil leak everywhere I'd go I had a puddle of oil left behind, well today was nice weather and I actually had time to look into it. Climbed under the truck and saw oil down the side of the engine, popped the hood and I could tighten the last valve cover bolt with my finger, tightened that up and no more oil leak! Thank the lord, it was driving me insane recently.
