Hooked up the boat trailer and have no running lights. Blinkers and breaks lights work fine. Verified with a meter that I'm not getting power to the running lights on the plug on the back of the truck. Checked all my fuses on the regular fuse panel and no problems. The owners manual refers to an Auxiliary fuse block under the instrument panel and to the left of the steering colum. Anyone have any idea where this is? All help will be greatly appreciated.
