03 Sierra wires:

04 Silverado:

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

 

nevermind - got them working - matched up the colors and used one of the Sierra's black grounds

 

3 > 1 so chevy >gmc sorry, facts of life

 

You can keep those extra wires... we'll just enjoy our 15% better production and quality, not to mention GMC workers are happier than Chevy workers

 

wait.....so if 3 is greater than 1, and the GMC has 3 wires while the chevy has 1.....isn't GMC greater?

actually chevy does have the lights figured out better than the gmc having only 1 ground going 'series' to each of the 4 bulbs - whereas the gmc's have to run 3 separate grounds all the way from the bulbs to the connector

anyways, this is dumb

 

lol wow u definatly confused me.

 

lemme know if you want to trade.
