thanks for the heads up on this Tow Ready 7 pin-7 pin adapter for LED trailer lights.
GREAT to see you tried it on a whim and it works. will have to grab one myself one day soon.

PS: great write up on the Tekonsha Prodigy RF.
I have one as well as I did not want to splice into my X5's wires either. LOVE the product/freedom it provides.
