I am looking for a circuit that will allow one to hook a trailer to a modern car. Something similar to this unit from eTrailer. I would like to set this up on 2 or more cars so for $65 each I am willing to take a look at it.
I do not think I have PWM or multiplexed wiring. I expect the heart of this is 3 mosfets but am unsure of the short circuit protection. Maybe a resetable fuse for each of turn signal and running lights.
Features:
Short circuit protection safeguards itself and the tow Lincoln Town Car against harmful electrical shorts and mis-wire situations
Virtually eliminates draw on the Lincoln Town Car taillight circuit
Taillight circuit has been upgraded to work with Lincoln Town Car using PWM, allowing converter to turn on fully giving trailer maximum light brightness
Powers the trailer's stop, turn, tail and running lights directly from the tow Lincoln Town Car battery
Unit prevents feedback from trailer to Lincoln Town Car system
May be used on 2 and 3 wire systems
When used on 2 wire systems, brake wire on harness must be grounded
Adapts a 3 wire system on the towing Lincoln Town Car to a 2 wire system on the trailer
Will work on Lincoln Town Car and trailer with either LED, incandescent, or standard bulb taillights
Works with most Lincoln Town Car multiplex wiring systems for lighting
