Since we've talked on multiple other threads about this, and that they are still on the blink, let's see if we can collectively get these working for you so you don't have to rely on hand signals!
Oh, and as for the discussion about putting some wire loom on those trailer wires, here's how I did mine. And yes, I'm shamelessly plugging WoodSToc.
I had hard loom coming out the side of the bike into the expandable soft loom, but when I put the side case on it jammed it up, so I had to remove it. I'll tuck and tidy the soft loom into the body later. Velcro holds the loom & wire to the hitch in 2 spots.
Drilled the hole in the Tupperware with a step bit and it feeds right into the tail section by the ECU where my relays are.
YMMV.
