2006 W900 lights are haunted. Help!!!

Use a light tester to check the pins on the pigtail to the trailer. If you're getting current with everything off, then disconnect the pigtail from the truck and check the pins on the back of the truck.

Still getting current where the pigtail connects to the truck, go under the hood and disconnect the pigtail from the fuse box and check it there.

I only suggest this route because once my parking lights wouldn't go out with my keyswitch on and it was because the pins on the back of the pigtail receiver on the trailer were corroded and the constant on power from the ABS was jumping over and back feeding up through the electrical system .
