Re: 72 K20 unknown wire??

Any chance you can post a SPID pic? Could be the tie-in for cab lights, for example, but I don't know how the truck is equipped.

Easiest way to know for sure would be to follow it back to the fuse bulkhead and let us know which cavity it comes out, that way we could determine what it's most likely for. From position and color it's tough to know...
