AuxBeam Contoler wire harness question.

So I found out that I have no 12v switch fuse options under the hood today after I pulled the wiring through the firewall. The auxbeam controller harness has a 4 wire harness. Black/red/green/blue. Does anyone know off hand if it stands as the red is power black is ground and the blue/green are the signals to the controller? I'm looking to tap into the power circuit of the auxbeam inside the cab to a switch signal and then T off at the auxbeam module to turn it on once it sees the power signal and I won't need to go back through the firewall? I hope this makes sense.
*I can't figure out how to correct the spelling in the title *

 

I hope this may help with explaining what I want to do if possible.
