First off I want to buy this grille but will I have to mess with my wiring harness to put this grille and head light kit in? Thanks a bunch, what I have now is the old style grille like the W/T version.

 

sorry the link was wrong its this grille link

 

The wiring is not hard since you already have the wire in place, but you will have to purchase the headlight pigtails for the new type of headlight. Your current headlight has 3 wires (ground, low beam, and high beam), the new headlights are have 2 wires a piece (ground and low beam or high beam depends on the light you are working with). You will have to make a good connection (I perfer soldering with heat shrink tubing versus the butt connectors) for the ground to both headlights, and the high beam wire needs to go the high beam bulb, the same goes with the low beam.

 

I have 2003 DuraMax Diesel 2500HD, had wrecked at front end and reconditioned body.

The headlamp (dimmer) at driver’s side, strong bright and passenger side, weak low. When I turn high beam switch is same as dimmer headlights.

I found the two grounds (-) attached onto frame beside at under front left bumper. What wrong with it?
Have you experinced with that situation? I need your help to solve with it.

Thanks for feeding back...I appreciate it

I think you might have 4 low beam headlights in your truck, pull out the headlight assembly and check the bulbs ( 9005 - high beam, 9006 - low beam). With one low beam being dimmer than the other,this could be an old bulb.

Did you ever install a headlight conversion which make all 4 lights burn on high. If you did then you have a couple of burned out bulbs.

The wires connected to the frame is correct, however you might check your ground wire going from the battery to the frame. The ground wire from the battery connects to the motor and frame. The frame connection might be located on the driver sided under the radiator support.

If this don't help get a voltmeter or test light and make sure you have power going to all the headlights, and also check continuity from the battery ground to the headlight.
