Flasher relay
#2
#4
brake lights are a simple in-and-out on the combination flasher. There are no relays or anything in the path.
Almost sounds to me like you have a short on the right rear section of wiring, faulting out the onboard chip. The CF receives power from the brake pedal switch.
To test it out of the truck, place the combination flasher with terminals facing you, and the side with the four "mini terminals" towards the top.
On the right side, apply 12 volts to the middle-top vertical blade between the mini-blades (brake light in). Attach your test light or multimeter to ground, and place the positive probe against the "middle right" horizontal blade, which is right rear output, and the "bottom left" horizontal blade, which is left rear.

Keep in mind this is looking at the socket. You'll want ti mirror it to work with the CF.
Pin A5 "ground" is not populated on the factory harness; there is no direct ground to the CF. It grounds through the lamps and the turn/hazard switch.
