wiring 2nd read / rv cam , need help finding wires by fuse housing

Does anyone know where the wiring to the rear cam is , when you are looking under the drivers side /fuse box . I am hard wiring an RV cam and need to identify these wires so that i can tap into them. I am done with wireless crap. I have already run the wires from the fuse area, back to the tailgate. I know the colors of the wires, Took the rear cam out and took a pic , I just cannot find those colors under the dash. Any help would be appreciated . As a note . I already have installed the anytime front cam , with the switch , and am able to see the rear or front cam when driving .
