3rd Gen Shell Brake Light Wiring

I've searched with no success, I'm looking for a COTS connector that will serve as a pass through to the taillight, with a split to power my canopies third brake light. This is because I'd prefer not to hard wire the existing vehicle wiring and a part of this sort should be relatively simple and cheap. I'm guessing I'm going to have to make one, but if anyone knows of this, please let me know.

 

Anyone know of something like this? I found this below, but I don't believe it is the correct connector.

I believe canopy dealers/installers use what you're describing for their installs. I'd check with a canopy dealer. You could also modify a wiring harness designed for a 4 prong trailer plug. (Just use the brake and ground wires). They're plug and play with no splicing or cutting.

 

Interesting, I will have to double check but I think the 3rd brake light in my Alucab only has two wires, so I may not have a running light, only off or on when brakes are activated. Something like this would definitely make powering it easier though.
