OK let me start over. The set I installed was on a Roadglide so it contains 2 H4 bulbs that switch from high to low. So when so turn on the ignition the relay picks up and fires both lights. So main power is ran from battery to relay to balast. The headlight wiring pickup the relay and switches the lights low to high.
Ultra will have to unique light circuits for the high and low beams. I would still power lights from battery to relay to balast.
Be glad to help install.

I'm only going to install one for the low beam on mine. It took me a while, but I finally realized that I can always add the high beam at a later date, and at that point, the installation should be a real snap, since it's my second time around.
I was really hoping that by this time, someone with the same exact bike as mine would have done this same install, and posted it all, pic by pic, and step by step, of what setup ends up working perfectly...like showing exactly where to secure the ballast and where to tie the wires to and where to run the wires too, etc. Did I mention that I like paint by numbers also? Anyway, if I grab a conversion kit, I'll give it a shot and when I get stuck, I'll be on the forum looking for a bailout. Or I'll just put it all back together and call you and let you know I'm on my way to Erie.
