I'd suggest cutting the low beam headlight wire and intercepting the ground signal wire at the switch. So as to bypass the body control module altogether, unless you want to retain autolamps.
Thanks all. The daytime running light at 7v and fulllow beam headlight at 12v is run on the same wire. The high beam is a second wire. If I cut the wire I would have no headlights. I will be using LEDs for the daytime running lights hooked up to a 12v ignition source. I just need to drop tge 7v on the main headlight wire so the HIDs are not on at all ...
The easist thing would be to remove the Daytime Running Lights (DRL) resistor and leave that connection open. Most F150s this simply unplugs as a module. If you ever change your mind you simply plug it back in. But I would be very hesitant to run my HID ignitor modules on 7v all the time. Without knowing what year of truck, I can't tell you where exactly ...
