Wiring in third brake light on bestop help.

Thanks for all the help guys. I managed to wire it correctly with the correct advice!

 

Good job! Did the brake wire end up being blue or green/red?

 

It was blue on my truck.

 

Im wanting to do this if I show you a picture of my tail ight wires can you help me figure it out how to wire it? I have three wires on the light I purchased. One is dim one is ground and other is for bright

 

Dim = TAIL
Bright = STOP

Tail lights connector:

 

So which wire to which from the pictures

 

I just saw this! Thank you it did not show up in my notifications..

 

If you don't want to peal, solder n seal or T-tap:
