This Headlight Adapter requires NO splicing of any light wires on the GM Truck. Plug and play. Visit EZ Match Go through the steps as if you wanted to buy a new plow for your truck. Pick any plow, it does not matter, only your vehicle information matters. At the end, it will give you a list of part numbers, including the correct Headlight Adapter part# for your vehicle. 07333 also includes (2) "Low Beam Cancel" modules. They are installed in the Module "C" socket, and the C Harness is then connected to it. GM trucks light the low beams when the high beams are turned on. This will overheat the "common" wire in the plow lights. So Meyer uses the Low Beam Cancel module to prevent this from happening. 07347 Modules manufactured after December 2013 have the low beam cancel built in, and the external Low Beam Cancel modules do NOT need to be installed.
