Make a dual FPDM harness and run 2 FPDM’s, 1 for each pump.

I think the upgraded FPDM’s were done by black306 I believe his name was.

This looks like the one I used when I was looking at going to a dual FPDM set up.

This is the one I use.

Mine was all plug and play. The female FPDM connector comes from a 1998-2004 F-150 door harness. I cannot put my finger on the exact connector part number at the moment. The male connector for the second FPDM is MOTORCRAFT WPT504. Then you need a 30 amp relay, an inline 30 amp fuse, and 12 GA wires for the rest. Out of each FPDM male connector, you will run new wires to feed each pump. 1 FPDM for each pump. See my images below of how mine looked. Literally unplug the stock FPDM, plug in the harness, run 2 wires to the pumps, and then a power wire to the battery.

I snagged the plug for mine from a Crown Vic in the junk yard. If there are any still in there.

I can see the female plug being able to be found as there are plenty of returnless cars in the Ford lineup. My concern is the female connector to connect the original wiring harness connector to the new harness you are making. I would appreciate the years of the F150 that the plug may come out of or a part number if anyone has it.

I also cant believe the prices of the male plug new... Crazy.....

The female connector is found here on the door of 98-04 F150's. Might also be found on F250's too, not 100% sure on that. I also cut them out at the junk yard.

What pumps you going to run? GT pumps with upgraded feed line will support 600 hp without a BAP.
