I took on the task of putting the wiring back together today and had all nicely marked but one wire in the headlight bucket. The wire that comes from the main harness is brown and connected to it is a yellow wire about 8" long with a black piece of shrink tubing on each end of the connectors. The wire goes to the tail light end of the harness. I'm wondering what it hooks to in the headlight bucket? Climers doesn't even show it in the wiring diagram.
