I bought this Trailer Wiring Adapter from Keith at RideTime
http://www.ridetimetechnology.com/qc...er_adapter.htm
so I would not have to splice into any of the bikes wiring harnesses.

Problem is I am going to have multiple wires for each of the connections instead of just a one to one butt connection. I am looking for different butt connectors that will work for multiple wires spliced to one wire or other ideas how to do this. Below are the wires from the harness and how many I need to connect.

Ground - 7 wires
Run - 5 wires
Brake - 5 wires
L. Turn - 3 wires
R. Turn - 3 wires

These are all pretty small gauge wires but not sure what gauge.

Only thing I can think of is like a water proof wire nut?

Thanks

I use one for my tour pack wiring myself.
What are you attempting to do , you didn't mention if you're going to replace the existing lights or just add on leds.
I have the QC connector plugged in before the badlands module (bike harness side).
This way I could control just the rear fender lighting with the module and the tour pack wiring would get tapped off the QC connector.
For most setups , you would only have to run 2 wires into the tour pack (directionals) and use all existing wiring for the rest.
The led lights draw very little power , so you can re-use the existing ground in the tourpack.
I soldered and shrink tubed the wiring in the tour pack as the wires are very small and easy to solder.
If you were to replace the existing lights , then the stock wiring would be PLENTY large enough for any led lighting you could do.

Thanks Mick, I am replacing the rear turn signal bar and adding even more LEDs but can not figure out the best way to connect multiple wires to "1" wire. Even like the first example with the ground I can twist the 6 ground wires together and then twist the single wire from the adapter around that and solder but then how to seal it up? Not sure if I get some heat shrink that will be big enough to fit over the 6 wire bundle if it will shrink down enough for the 1 wire. Then I am not sure if the heat shrink around the 6 wires will shrink down enough to seal around each wire so moisture will not get to the soldered connection.

 

If you're connecting lets say 7 tiny wires to 1 larger (16 gauge) wire , get a butt connector that fits the 16 gauge pretty tight , twist the 7 wires together and crimp them on the other end.
Put your shrink tube on before you start , marine type shrink tube has a sealant that oozes out both ends when it's heated and gives a waterproof seal.
If the 7 wires are still too small to fit properly in the crimp connector , turn all 7 back to double their size for a better crimp.
If you can't find sealant type shrink tube , use silicone sealer at the ends of the butt connector before you shrink the tube for a great seal.

The only right way is to solder and shrink wrap all of your connections. I've got plenty of LED's on my Ultra and everything is soldered and shrunk wrapped. The solder will make it a waterproof connection and the shrink wrap will keep it from shorting out.

 

OK, I am down to just twisting each set together, sodering and cover the joint with Heat Shrink tube.

Twisting each set together and using a Posi-Twist connector

Using something like LeverLockz or CageClamps but can only find them up to five wires so will have to use two for the big one.

At least with the Posi-Twist and the Levers I could add more later but just do not know how secure that is going to be.
