Fiddled around with things to right and got it all figured out. I wanted to be able to control the lights by themselves without linking to the high or low beam. What I did was ran a 12v switched source that comes on with the ignition to pin 1 of the factory switch. Left pins 2 and 5 alone as they simply illuminate the switch itself. I connected pin 4 to # 86 on the relay included with the kit. Ran the other wires from the relay as directed and now I've got working lights.

Grounded the relay to the firewall, grounded each light individually to the frame and retained the factory ground for the switch. They outshine the high beams by a ton which surprised me.
Common upgrade in some 4x4 circles to do just that. My bronco would only get 10-11.5 volts at best. Just imagine our headlights with full voltage.....
I could be wrong but im pretty sure we dont get12-14 volts to thelightbulbs.
