Looks to me to be;
A=Black, B=Dark Blu, C=Red, D=White, E=Yellow, F=Dark Grn.
Might check at the tail light end and see what wires you have there. Mine came with trailer hitch and trailer light wiring installed, don't know if they all did.

Hi Ho: Have fun with the toy trailer. I think you will be just fine if you are willing to go slow and shift down on the upgrades. Forty years ago when I was really young and dumb I had a Mercedes diesel (85 hp) and a 17 foot waterski boat. I towed that thing all over the western US. I still remember going over Donner pass at 25 or 30 mph in first gear.
More recently we have trailers similar in size/weight to yours. The snowmobile trailer weighs over 5000 lbs. and the boat weighs closer to 6000. We have a 35 foot Itasca with the Ford Triton (300 hp) and do just fine even here with 7% grades all over the place. Hey, all the fun places are in the mountains. Just make sure the brake system works like it should. And be sure to disconnect in the driveway to avoid a bunch of skid marks.
Hi Ho: I expect since the hitch is class III that 5000 is the theoretical limit. Keeping about 500 lbs. on the hitch is important and should be checked.
Someone suggests getting tires with more plie) (load rating G), but then the wheels and axles are probably overloaded. As you know, ratings are worst-case situations. If a panic stop is required, what is really important is that tires, brakes, etc. all work as they should. Just cruising down the road is really not that tough.
Keeping enough air in the tires is also important.
Hi Dirk. Things have changed. Now it will be 4 bikes in the toyhauler. The tare weight of the toyhauler is about 2800lbs. I hope I will be in range. We are going to leave the toyhaulers tanks empty.
