Snowbear Utility Trailer wiring??!!! ack!

[KazariK]

Good day all!!

So, first time here..

Here is the deal. I have a Snowbear Utility Trailer I got from Canadian tire. The original harness on the trailer was heavily damaged by a friend and replaced with a 7 pin connection as that is what was wired into my Mazda 3 (no flipping idea why?!)

anyways, this week the 7 pin got heavily damaged so I decided to change it out and the one in my mazda to a 4 wire flat connection.. Great, got the mazda wired and tested and all good..

I went to wire the trailer and WHAT? there isnt 4 wires but 5!
Now, no big deal right? well, everything I have read said that I should have the following wires - Yellow, Green (left/right), Brown (markers), Blue (brake signal) and White (ground).
BUT, thats not what I have..

I have the Yellow, Green, 2 brown, white..
Now, a yellow and brown are tied together, a green and brown are tied together and the white on its own.

Now I have been trying to figure out how to wire this to a 4 wire harness.
At first I thought the browns should go to the Brown on the car, BUT I just had a thought.. are the Browns maybe the ground? and the white is the marker wire???

Darn it! its to cold outside to go test that theory! lol
Your thoughts?

I like these trailers. I use one occasionally; one can load the hell out of them (enough to blow-off the tires) yet they are light and compact.

The 5-wire system is compatible with cars which use separate amber turn signals and red stop lights. Chances are the trailer was wired up for a car with integral turn and stop lights, hence the wires were tied together.

The easiest way to fix this is to get a 12 volt, low amp power supply ( a battery charger is ideal). Look at the tail lights themselves, and you should be able to see if the white wire is really hooked up to ground. Then clip the negative terminal of the power supply to the ground wire and start applying power to the other wires, and see how the lights illuminate. From there, you can work out which wires do what and wire the connector accordingly.
