The GMC Illuminated Grille Emblem and mirror puddle lights come as plug and play accessories.

The Grille Emblem comes as one piece with a wiring harness. It does not come with instructions, but it is pretty self explanatory.

The wiring harness will plug into the new grille emblem and run along the shutter frame, down to the back of the left (drivers) side headlamp. The headlamps harness will plug into the new harness and the harness will plug into the headlamp.

Remove the upper shroud. It is held on with plastic clips. Remove bolts on top of grille.

Grille has 4 tabs that need to be released after bolts are removed. One on either side and two towards the center. Pull up and out gently on grille. This will allow you to get behind the old grille emblems for removal.

The old emblems will have to be removed one by one. Each emblem has tabs that must be released from the grille. A flat head works well, you may need an extra set of hands to pull back on the grille for access.

The upper part of the bumper that fits up in front of the headlamps may come out as you pull back the grille. Each side is fastened by 2 clips, it will easily pull out and pop back in. Make sure the clips go in straight and not from the side when reassembling.

Remove the first 6 bolts in the wheel liner. Remove the bolt in the bumper and pull bumper away from bumper bracket. This will allow you access to the back of the headlamp assembly.

Run grille emblem harness through the back of the grille into the new grille emblem. Push in the new emblem into the grille. You will hear/feel it click into place. You will now run the harness up through the top opening of the shutter frame. Make sure it is through the top of the frame, and not through the top shutter opening.

The harness is shown running through the top of the shutter frame, (not the shutter opening) The harness comes with clips to clip it to the frame to hold it in place. The harness should not be visible through the front of the grille.

The harness will then run up and over the radiator support and drop down behind the left headlamp assembly. Pull away wheel liner and unplug headlamp assembly. Plug in your headlamp to the new harness and plug in the new harness to the headlamp. Zip tie the harness to the lower fender bracket.

Once your grille is installed, hit your remote or turn on your headlamps to check. Push left side of bumper back into the bumper bracket attached to the lower part of the left fender. Bolt the bumper back to the fender, and re install the wheel liner screws. Push grille pins back into place and re install the grille bolts. Re install the upper shroud.

Installing the mirror puddle lights is fairly simple. To remove the old lights, use a small flat head to gently depress the clip to remove. Unclip the wire harness. The puddle lights are coded on the directions. Blue label goes to left mirror, green label to right mirror. Unplug old light and plug in new puddle light. Reinstall by clicking into mirror.

Awesome step by step tutorial!

So jealous these emblems are massive compared to the 15-20s. Only way it would work is if I got an aftermarket grill and honestly the aftermarket selection sucks.
