73973-1 2017-2019 Ford Superduty Headlight Harness 11 Pin Quad H13 Lights 3 Port Kit Truck Side Light Adapter Western Fisher SnowEx Blizzard

This is the newest version of 73973, now # 73973-1. Truck Side Light Wiring Kit for trucks that have quad H13 lights used on 2017-2019 Ford Superduty trucks.  This is for 3-port modules only. You get 11-pin light harness 73970 and the plug-in headlight harness 73972-1. If you are swapping trucks, you may only need the light harness. We have that listed separately. We have all the others kits available, too.

** The relay pack on this harness is very large and it works well on the gas trucks but, we found it hard to install on a diesel because of finding room for the relays. 

This new version has the relays built in to it and no longer needs the adapter wired in like the previous version. 

This is used with Western, Fisher, Blizzard and SnowEx.

Western went from relay wiring to 4-port wiring, to 3-port wiring and now Multiplex wiring. We have all of these options available. We will also trade in your old wiring.
