I have a 2001 TL, and I just installed the 2002+ taillights. When I tested them out...I don't have any brake lights!

Here's more information:
- pressing lock/unlock on the key fob makes the brakelights blink...so the lights work!
- the signal lights work
- the spoiler brake lights work when I press the brakes...just not those on the tailights.

What could I have done wrong? I thought it was simple enough. Here's a summary of the procedure:

- Take out original tailights and wiring harness
- Install the included lights into the new tailights wiring harness and plug them into the taillight enclosure...turning clockwise until they locked into place
- Install the new tailights into the car.
- Connect one (1) power connector per taillight.

Additionally, I noticed that on the original driver's side taillight, there are 2 power connectors. One plugs into a box which isn't present on the new taillamps...so I left that disconnected.

Also, I got the taillights from Tim ... so it's the complete upgrade kit with harness and light bulbs.

Please help! Thx.

 

There's your problem. The 'box' must be moved to the new tail light.
