Hello brethren truck lovers, I did a basic search and came up empty handed but hoped someone could help or lead me in the right direction.
I have a 2010 F-150 Scab FX4, was trying to locate the correct wire and get it connected to the correct source to keep my driving lights on both low and high beams ? As everyone knows the lights cut out when high beams are used, I want to eliminate this in-activity.
When I'm going back and forth to work here in Deer Country I want to try and light up as much road and shoulder so I can to avoid costly mishaps.
I know what it boils down to is a constant 12v supply being connected to the trigger wire for the relay to turn the lights on.
My issue is it's F-ing Winter here and I'd like to make this as pain-free as possible without having to reserve garage time and try and get this done outside on a decent day in short order.
FORScan is software you can down load from the net and along with a plugin for your OBD port, modify your truck's as built software. Dealers use a system called IDS.
So what I did to keep the factory fog lights lit during high beam use, is added a wire coming off my AUX high beam LED lights (they use a relay) and wired it to the positive side of the drivers side fog light. This just back feeds the fog light circuit and keeps both lights on. I have not had any issues with this set-up in over a year of running it and here in Alaska I run my high beams A LOT in the winter months.
