I have just purchased a Toyota 4Runner. The harness for towing that came with the truck does not support a pin for my surge breaks. I own two boats and two trailers. One is for a small skiff that does not require surge breaks. I ended up running an addititional wire off a back light to pin into the coupling for the larger boat when necessary in my old car.
I would like to have the simplist set up I can for my new truck so that either coupler from the two trailers will work.
Has anyone else dealt with this problem that has a solution to share.

On further inspection of my truck I see that there are two places to connect the wiring for the trailer. One is the standard four pin connector that will work for my small boat and the other is, I guess, a seven pin connector. Part of my confusion is that this second option I simply a very large female unit in which a single large male unit is plugged in.
The boat with the surge breaks has an old time five male pin connector that plugs in. Can I purchase some sort of universal male connector that I can attach the wires that come from my trailer into that will work with this?

Well, the solution was simple. The large, single female unit that came with the truck is designed to take a number of standard adapters. I simply had to purchase an adater that would include interfaces for both the four and five pin plugs coming from my two trailers. There are plenty of vendors on line that sell these things. I got mine from etrailer.com
