HDC Fuel Pump Harness Kit (Third Pump Add-on)

This kit works in conjunction with the HDC Billet Hat kit (sold separately) to allow independent 3rd pump control in 99-04 Gen 2 SVT Ford Lightnings, 00-03 Ford F-150 Harley Trucks, & 97-03 10th Gen F-150's (& 04 Heritage). This leverages the billet hat kit power relay module, and hooks up to allow 3rd pump control triggered off any method you choose with a ground trigger (hobbs switch, toggle switch, WOT switch, etc. - not included). Color directions included. Photos show 3rd pump relay kit by itself, and 2 photos show it used in conjunction with the billet hat kit (sold separately)

When used for Triple Pump Use with 2 pumps constant 1 pump triggered, the HDC Billet hat kit powers the 2 constant pumps and the 3rd pump relay kit powers the triggered pump. This kit can also be used for Dual Pump Use with 1 pump constant 1 pump triggered for folks with a billet hat where 1 pump is primary/constant on (instead of both pumps), and the 2nd pump is triggered by something like a hobbs switch (instead of a third pump), you can simply use the HDC OEM hat kit for the 1st pump, and the HDC 3rd pump relay kit for the 2nd pump, rather than the HDC Billet hat kit.
