Hi,

Not real good on wiring hope someone can help.87 k2500 has turn signals,brakelights,turn the headlights on,have them but no rear lights.Rear wiring was worked on from previous owner that installed a hitch/harness for the trailer wiring.I eliminated that and have a brown wire that can not figure where it goes.In the wire loom by the rear bumper are dark green wire,light green wire,yellow wire and a brown wire.There is also another brown wire that is bare and if I wire it direct I have running lights without the headlight switch pulled.So where does this wire get installed into the headlight switch circuit ?

Thanks for any responses Bob J.
