79147-1 3-Port Truck Side Light Harness Wiring Kit 2018+ Toyota Tundra LED Lights Western Fisher Blizzard SnowEx

This is the Truck Side 79147-1 Light Wiring Kit for a 2018 and later Toyota with LED headlights. This is for 3-port only.

This kit has a special harness because this truck runs the low beams along with the high beams and they installed a relay to disarm the low beams in the headlights so you do not melt your plow lights. 

You get the 8-Pin Plug-In LED Harness # 79146 and the 11-pin plow light harness 29861-4.  If you are swapping trucks, you need this kit. Both these harnesses are specific to this truck. If you need the complete truck side, we have them listed too.

This is the newest version of the harness with the sealed relays. 

This part is used on Blizzard, SnowEx, Western and Fisher plows.
