Hi, I am going to show you how to install ANZO headlights in a 2008 GMC sierra 1500.
Step 1: Taking Plastic Shield Off
You are going to want to take off this plastic piece that is on top of the grill. There will be tabs you must get under with a screw driver and force them up to get the shield off.
Step 2: Prep
You are going to want to get your 10 millimeter socket, extension, locate your two 10mm bolts. Slowly loosen the 10mm bolt, then locate you connector wires which connect to the headlight.
Step 3: Wires
Once you have the wires located your going to want to disconnect them from the wiring harnesses they are connected to, then take those wires and move them out of the way and take your headlights out.
Step 4: Finishing
Once you've done all that and the headlights in place connect the wiring back to the new headlights, then put the 10mm bolts back into place and tighten down, take the plastic cover piece and put all the little tabs back in the holes, once that's done turn your headlights on and make sure they work properly.
