996 C2 Tail light swap over to LED Tail light Tutorial

A few simple steps to breeze through your tail light swap. I bought the smoked Taiwanese version. I hear there is a Chinese and a German version. I got my set from a seller on fleabay (ebay). I paid 375 with shipping. They were packaged very well, and undamaged upon opening. As described - no instructions. Some people will unplug their battery for any electrical work. I did not. A: Open Engine Hood You should see the one and only 10mm Bolt holding each tail light housing in place. Remove them. B: The light housing will pull towards you and slide off the front interior hook. C: Turn it over in your hand. You may unplug all of the light sockets by turning the socket counter-clockwise until it stops. D: Its as simple as pulling the old lights bulbs from the plugs with with a push and twist. E: Then plugging in the plugs from the new housing. You can use my pictures here to see where each plug goes. They go in different sockets when you use these LED tail lights. Note: The small parking bulb does not go back into its socket, you can see how it is stretched across for the other plugs to reach. Also, you must leave one clear bulb in for your backup light. And if you use your European rear fog light, you will need to leave a clear bulb plugged in to that socket. You can use the bulbs that were already there. No need to buy new ones or special ones. F: Fit the housing back on the front hook inside the well. Finish by sliding the housing in and replacing the 10mm bolts. One bolt for each side. They appear nice and bright. Fitment looks almost stock. I wish I had the german ones to compare.

I just completed installation of the made in Taiwan smoke led tail lights on my MY01 C4, and I wanted to share some information I hadn't seen elsewhere. I have also attached some photos: (1) before; (2) half and half; (3) & (4) after; (5) connection diagram for new tail light housing; (6) transparency problem; (7) - (9) truck door edge guard solution.

With respect to the small side marker bulb wire that has caused some to blow fuses, I just lined up the red wires on the male and female ends and plugged them together (photo 5). No blown fuses, hyperflash or ABS/PSM warning lights.

I had not seen a good diagram of how to hook up the the lights on the new tail light housing, so I have labelled how I hooked them up in photo 5 (note: top of photo is bottom of tail light housing). In a nutshell: (1) small side marker bulb wires (far left) plug into the corresponding wiring harness connectors (as others have commented, this does not get plugged back into the socket); (2) double light led leads connect to black brake/tail light harness sockets; (3) single light led leads connect to orange turn signal harness sockets; (4) existing reverse light sockets and bulbs are connected to the lower (top of photo) clear chamber; and (5) fog light sockets are connected to the upper (bottom of photo) clear chamber (I used the amber turn signal bulb for the fog light on the driver's side so it would not be confused with a reverse light).

After installing the new tail light housings, I discovered a design flaw: unlike the stock lenses, the aftermarket lenses (at least the smoke ones) are transparent at the edge. As a result you can see the unfinished edge of rear quarter panel and the tail light connecting grommet through the lenses (photo 6). After my initial disappointment, I started to think about a solution since I really liked the lenses otherwise. Initially, I thought about using lens tint spray to darken the edges. Given the limited space to work for proper taping, the fact that the surface is grooved, and that this solution would be non-reversible, I decided to use a different approach.

Door edge molding to the rescue (photos 7-9). Applying black rubber door edge molding to the unfinished edge under the lenses provides a finished look and hides the transition from the body to the lenses. This was a relatively easy fix, and I am pleased with the result.

Overall, I really like the look and functionality of the new tail lights.
