I wired my RAV4's lights to work exactly the same as the coach when hooked up. The coach brakes light the toad's two red brake lights plus the high center brake light, and the coach directionals light the toad's amber directional lights. I used diode packs, and all of the connections were made behind the driver's side front kick panel, eliminating the need to route wiring all the way to the back. My coach to toad umbilical cabling consists of a six conductor coil cord set and a four conductor coil cord set, handling the lights, the toad charge line, the Remco pump controls, and the coach dash indicator LED for the ReadBrute/ReadyBrake system.
