Reading this has made me wonder something, I've not tried it, but may, would a 4 wire trailer plug and harness, with the same plug at both ends, be able to back feed your tail lights on the towed vehicle without needing to add other harnesses? Likewise would the same thing with 7 wire plugs on both ends maintain the towed battery?
Or do the electronics and diode setups in newer vehicles make that impractical?
Basically I'm asking about tying the trailer plugs on both a motorhome and towed together.
