What you will do is use harness # 331-TPH-010 which plugs into a port on your 2018 Chevy Silverado 2500 and is compatible with the Redarc Tow Pro Elite part # RED44FR. But you will need to remove the blue wire from the end that plugs into the truck. You will then take a length of wire, # 10-1-1, and connect it to the blue wire you removed from the connector.

Route the blue wire through the firewall, under the truck, and to the trailer connector. Avoid hot or moving parts like suspension and exhaust.

At the trailer connector, remove the wire in the 7 oclock position (looking at the back of the connector where the wires attach). Tape it up and stow it out of the way. Then attach the wire you ran to the 7 oclock position. This will bypass the factory controller without causing any dash lights/error messages to appear.

The 10-1-1 wire is sold in lengths of 1 foot. So if you needed 20 feet you would put 20 in the quantity box.
