What part of your pickup is this located? Under the dash?

 

Yeah its under the dash the truck aint mine but thats the plugs thats hangin. I was thinkin it could be the neutral safety or sum but i dunno ill keep searchin diagrams an such.

 

Whats on the other end? Looks like a switch from here.

 

looks like its coming from the convivence center block.

 

Check to see if any of the wires get power when you press the brake pedal (key may need to be on).

I don’t think it was very common in the 80’s but it’s possible it’s an upfitter plug for a trailer brake controller.
