Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly: that's going to save you time and money. Thank you and enjoy the video.
In this video we're going to show you how to replace the taillight, either replace the taillight bulb or the procedure for replacing the entire tail light. The only tool you'll need is a 10mm wrench or a socket wrench with ratchet and maybe a pair of pliers and a flat-blade screwdriver.
Starting with your tailgate, open there are two 10mm bolts on each side for each light. You want to remove those 10mm bolts. We'll just kind of speed through removing those. You can use a 10mm wrench or a socket and ratchet like I have.
Once you have those bolts out, pull it firmly. If you're looking to just change your bulbs, turn them counterclockwise. The socket comes out. The bulbs just pull out of the sockets. Your harness goes down into there. Up underneath you want to unplug your connector. There's a tab right here. You press and unplug. Then the connector is held onto the frame. You have to pull it off. Then this clip here that holds the harness on, you pull that off as well. You can get that from 1A Auto. It comes with everything including a harness and plug.
You see my old light is perfectly fine. I'm not going to go through all that changing out of the harnesses and stuff. To reinstall, I'll move it into place and make sure these tabs go into here and then down there as well. We'll fast-forward again as I thread those bolts in by hand first. I might have to push on the light a little bit to get the holes to line up. Tighten them up with the socket by hand. Then tighten them up firm with the ratchet.
We hope this helps you out, brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the internet. Please feel free to call us toll free 888-844-3393. We're the company that's here for you on the internet and in person.

Read me before you buy
Unhappy
June 12, 2022
Bought both right and left side. Read my review for the right side as well. This side the brake light socket was very tight and difficult to get the bulb in, but it did go. The fit was slightly off and stuck out towards the top so it didn't fit flush along the side. The kicker with this side is that the threaded clip that the screw goes into was missing. Making it completely usless. Read the small print too. I requested a refund and have to pay over 20 bucks to return defective items they sold me. I'd understand if I changed my mind or just didn't like them but heck I can't use either one. Been very satisfied with 1aauto for a lot of parts I've bought but not much anymore.
