Wiring Camper Shell 3rd Brake Light

I have wired this before but it was wired to factory taillights and would work as both taillight and brake light. I just bought AlphaRex Luxx taillights and want to wire the camper shell 3rd brake light to the OEM brake light harness. What wire should I tape into. I tried the green wire and it only lite up as taillight. If I tried the blue wire it only lite up when I pressed the brake is there a way to have it do both off of the OEM brake light wiring harness? this is for a 2nd gen Tacoma.

 

I would like to know too!

 

The camper light would need to be a dual filament lamp. One for Tail (dim), the other for stop. (brightest) or a module that combines tail and stop to a one filament lamp.

 

There was a member here that was selling brake and reverse light taps using factory plugs and such. I have one in my “I bought this because I might need it” box.
