So I was lucky enough to snag one of the last sets of harnesses from RetroShop and I promised JJ I would do a write up for those interested in installing a set when he gets the new adapters in.
What you will need:
- T25 Star Bit to remove tail light screws
- 4x Self Tapping sheetmetal screws
Remove the two screws from inside the bed of the truck using the T25 star bit. NOTE: If you have a tailgate assist you will need to remove that first before you will be able to get to the bottom screw.
Attach the new tail light adapters to the OEM pigtail. Connect the new tail brake light plug to the OEM tail light plug making sure the red wire on the adapter plug connects with the OEM tail light plug. Because the new adapter makes the OEM pigtail longer I took all the wires and stuffed them behind wall as seen in the photo.
Find a location where you want to attach the resistor. Because this resister is a little bigger and says that it will get hot when powered on I decided to place it on the fender part of the truck and keep it away from all wires and the tail lights. You will need to put two holes here. One to attach the resistor to the truck and one for the ground wire on the resistor.
Attach the plug on the resistor to the final plug on the adapter and then stuff the wires behind the wall where the tail light attaches.
Then run the LED tail light plug on adapter through the bottom hole of the frame and attach to the tail light.
Attach the new tail lights to the truck and put the screws back in place to secure it.
Here are some pictures and a video.
NOTE: These tail lights use a different type of reverse light bulb so if you used LED back up lights in your previous tails they will not fit in the new tails. Here is the picture of the new tails reverse bulb. I believe it is a 7440.
