I use a seven pin female connector to the coach with a four foot lead to four pin connector on the Toad front valance using the ground, tail light, left turn and right turn terminals of the the seven pin connector.
The wiring from the four pin connector to the harness at the rear of the Toad is wired directly into the corresponding existing wiring as ground, tail, left turn and right turn using diodes to eliminate back feed into the toad harness.
Seven pin female connector $3.99
Four pin male and female connectors $4.95
22 feet of four wire cable $11.00
Total $32.00 and two hours of my time.
Uses existing bulbs in the rear of the Toad, 10 years of operation no problems and total cost is cheaper than a custom harness from a national supplier alone.
