Atomic LED game changer

Perhaps some of you are familiar with atomic LED and their products. I used to have a replacement third brake light of theirs in my ranger that doubled as an Amber strobe light. It was pretty trick. I also wired up my reverse lights, turn signals and running lights with some relays, LEDs, and a strobe module. I was thinking about doing something similar on my tacoma, but instead of running a bunch of extra wires directly to the lights, I'd like to do something similar to this.

I contacted them and they said they are not interested in making something for Toyota at this time, so my question is, does anyone know where I can source the connectors to wire these in like in the link above? Also, a good schematic to find where all of my lights originate in the cab would be great. I'm wondering if @mesojdm has any input as he seems to be the resident electronic and lighting expert.
