This should be a all time boner!!! Who ever hooked up the driving lights on the grill guard used the blue wire in the fuse box in the engine compartment and un plugged it and hooked up the driving lights to it and used the trailer brake plug in inside the dash for the power supply second one over!!Took a little while to find it,Really didn't want to run a new wire , but had too find the problem ,leaving tomorrow to p/u trailer in N.C. 3 day road trip ahead to get there .
