What is this plug for?

[Johnnyz453]

Trying to get rid of things i dont need anymore. Think this plug is for cruise control. It is connected to a pretty long rubber-like tube. Just want to make sure its cruise control before i get rid of it. Its a 83 k10 with a 350 in it. Originally had a 305 though.

Not sure what it is but If it is cruise, I'd tuck it away. Never know down the road if you want to put a 5.3 in it and want to use the stock cruise on the steering column.

Where is it at, and where does it go to? Is there a cruise control servo still in the truck? It looks like either that or maybe the timing connector for an ESC distributor. Do you have that or regular HEI with a vacuum advance?

I'm suck at ID'ing wire color, but if the leads - from left to right - are:

DK BLU, TAN, BLK, LT BLU/BLK tracer & LT GRN. Then, yes - that is almost certainly the connector to the cruise control servo.

Check the P/N on the connector body. If it is a PED with the number 12020646...I would say it is definitely the CC servo connector.

It has the hei distributor with vac. Adv. It comes out of the firewall by everything else and goes nowhere. When i bought the truck it wasnt connected to anything.

Sounds like you nailed it.
