Honest question, what's the attraction to tying into the vehicle's lighting system, especially on anything that is CanBus or even later greater technology?
I can think of a couple different methods that are most likely cheaper, very simple and present no issues or considerations with messing with the OE electrical system.
Brakes, different story. I'd have those if really needed, but would doo what I could to not have to worry aboot that either.
Well, you need lights out back and there's only a few ways to get them:
* Add new bulbs into the tail light housings - requires new wires, bulb sockets, and drilling holes in the housing.
* Add external lighting - magnetic mount units. This doesn't work too well when the vehicle body is mostly aluminum. Then you've got to store them when not using them, and ensure that the wiring doesn't abrade the paint job when using them.
* Build a light bar that you somehow attach to the rear of the toad when needed - again you need to store it when not in use, and you still have to deal with the wire abrading the paint job.
* Use one of several "plug and play" wiring systems that use the existing wiring and lights - these work well, but as this topic shows, there are instances where specific vehicle issues pop up.
I looked at the CoolTech solution, which adds a switch to the existing wiring going to the rear of the vehicle - the lights are either powered from the toad, or from the RV, but impossible to power from both simultaneously because of the switch. I thought their kit was above my budget so I built my own: about $30 worth of parts and it's working well. I have a switch on my dash and put it in one position to tow and the other position to drive.
As for brakes - again I went with the simplest solution. NSA Ready Brute Elite tow bars have a surge brake built in to the tow bar so there is no need to add a portable box connected to the brake pedal, with a 12V line to keep the unit powered, or tie into the toad's hydraulic system. A simple cable from the brake pedal to the front of the toad is all that's required.
Other people prefer other solutions - that's the nice thing about this country: we have choices and aren't tied to a single solution!
