03 Sierra wires:
Green
Light Blue
Dark Blue
Brown w/white stripe
3 Black

04 Silverado:
Green
Light Blue
Dark Blue
Brown
Black (1)

Guy I bought them from said 'harness included' but what he meant was he just cut the wires and I'm left trying to figure out which match up - I know the obvious, match up the colors and just guess on the black which might be ground (maybe all 3 on the Sierra are ground and the Silv's just need 1 ground?)

I just dont want to blow anything up which may or may not even be possible - just figured I'd ask first :insane:

I wonder why He cut the harness instead of taking like 30 extra seconds to pull it out......

you know they are stolen when you buy them with a snipped harness:rolleyes:


it's not hard to wire them up anyways.... just colors to colors

connect all the colors to eachother

There should be only one black wire on you 99 harness and numerous balck wires on the 04 tails, so match all those up.
