what is this wire for?
 

still trying to tackle this taillight problem....ive got a 1984 k10 4x4 and i dont have any running lights. i looked at a schematic and i think this is for the running lights but not sure. just need someone that has had this problem before

Re: what is this wire for?
 

crap.....im talking about the brown wire that crosses over the red one

Re: what is this wire for?
 

are you running a tach?

it by-passes the fuse box completely, so that makes me think it's aftermarket something...

Re: what is this wire for?
 

brown is the running lights, yellow is a stop light , dark green is the other stop light and light green is the reverse lights.

Re: what is this wire for?
 

nope no tach, i cant tell by the schematic i was looking at if it was for the tail lights, it said there was a brown wire and then a orange one, im fixin to retrace the wires all the way back. and it doesnt totally skip the fuse box, i think it comes through the fuse box then out. i think its a open circuit.

Re: what is this wire for?
 

where does the brown wire go??? thanks man...glad i can still somewhat read a schematic lol

Re: what is this wire for?
 

into to the fuse block or the tail lights?

Re: what is this wire for?
 

ya..i just wasnt sure where at in the fuse box

Re: what is this wire for?
 

I think it connects to that lighter colored 25 amp fuse next to the orange 20 amp in your picture.There is a fuse box diagram on www.chuckschevytruckpages.com if that helps at all.
