FYI: if you are planning on using your center clearance light for a voltage source for the camera, you might want to try this in a test setup, and maybe measure the voltage available there with a voltmeter. I found that due to wiring voltage losses from the front umbilical cable connector to the rear center clearance light, and the amount of current that all of those incandescent bulbs were pulling, that I only had 7.5 VDC at the rear center clearance light. I swapped all of the clearance and taillight bulbs to LEDs, but that still didn't raise the voltage enough to reliably power the 12 volt camera. I had to get out my wire pulling rods from Harbor Freight Tools, and snake a 2 wire cable up along the rear cap side to the side clearance light, then over to the center clearance light. I wired the power into the rear stabilizer switch and installed a toggle switch for the camera in the rear stabilizer switch faceplate.
