How to disable the DRL on Canadian Trucks

On the Canadian FORD F-250/F-350 trucks, the Daylight Running Light Module (DRL) is bolted to the header panel behind the driver’s side headlight, under the hood. The battery/Air box may be in the way, making it difficult to get your hand between the battery, and header panel to unplug it. If the truck has been running recently, the resistor is going to be VERY hot. This is why it is inside a perforated metal cage. It acts as a heat-sink. There will be a wire that plugs into it from the bottom. Just unplug the wire and let it hang, or zip-tie it out of the way. Now you can upgrade your headlight harness and get better and brighter light.
