    New to the forum already gathered a lot of info from you guys, thanks.

    Just spent a coupe hours installing wiring on my 2000 chevy 1500. I followed the diagram off of westerns website to a t. Checked the routes of all my wiring multiple times. Brand new solenoid. Problem: vehicle lights are all on(both drovers lights are dim passengers are both on and low beam is normal), then when I turn on my brights only my passenger light is on bright(low beam is now off) and both drivers lights are still on (dim). Please help! First plow ever.

    Make sure head lamp plugs are on the correct lights, light blue and orange for low beam. Light blue and red for high beam. Be sure this is correct for the plugs on the actual truck lights and the light harness to the trucks factory light plugs. Also make sure your grounds are good.

    The plugs can't go opposite. They have single or double grooves. Any other options?

    I'm sorry I forgot to mention I purchased the wires used. Came off a truck exactly like mine and I have talked to the shop that took them off.

    If you are sure wiring is correct and grounds are good, I would replace the relays.

    I will be honest my red wire is just a straight wire. Is the diode necessary?

    We also wired the gray and purple wire to the same bulb on the drivers side. Not the same wire, but the same bulb. Could that bet problem? I just figured since it wasn't blinking it was my parking lamps.

    See I wired both drivers side to signal bulb. I don't think my parking light bulb works.

    I really hope it's this simple. Shops around here wanted $400. I did it in 5, but wrong lol.

    There's three wires behind the turn signal bulb I wired purple to one and then gray to another of the three

    You need to probe the wires to find out which park, turn and ground.

    I did. Is the turn signal and parking light the same bulb?

    If that bulb acts as both parking and turn. Then yes I wired that part correctly. I was just unsure because there are 2 other bulbs. Thanks Merry Christmas

    The brown wire is power to your headlight relays. You have 6 relays, correct? If you don't get power to the brown wire when you turn your headlight switch on, you'll never get the headlights to work properly. doublecheck your power and grounds at headlight GM changed the order in 2003, if the truck it came off of is late 2002 and newer, your positive and negative into the headlight adaptors is going to be different.

    Yes 6 relays. The wiring came off of an 01. I have a 00. I followed this diagram: page 6

    http://www.storksauto.com/docs/wp-content/uploads/2010/07/Wiring-Schematics-Western-unimount-Chevy-GMC.pdf

    The only thing I'm not 100% on is the diode in the red wire going from relay #6 that gets tapped into the orange or dark blue wire(headlights).

    Also, I'm unfamiliar with the object in he wire going from relay #2 to the fuse on the right in the diagram.
