Another What Are These Wires Question
 

So we are working on my sons 82 SWB and I've figured out all the wires with the exception of these three on the harness bulkhead. They appear to be tan, pink and brown, I have looked at several diagrams, but cannot find a color/location that match. Can anyone shed some light on them for me ? Also what's the plug below the bulkhead with the yellow wires ?

Have you visited this thread and downloaded the diagram? http://67-72chevytrucks.com/vboard/s...d.php?t=545416
