Coyote fuel pump/fuse panel wiring?

I am trying to follow the directions to wire the coyote harness into the Ron Francis fuse panel. First off my fuse panel looks different than the picture in the factory five manual(picture attached). I see my fuel pump relay control wire, it’s tan not orange. In my fuse panel it has another wire attached to it and the fuel pump relay wire starts in a slightly different location. Do I still cut the wire where they say so in the manual and attach the coyote green fuel pump wire? Do I move the the wire in the fuse panel to match the picture and get rid of the small jumper wire? If so do I then just pull out the short piece of left over wire from the fuse panel? As you can tell electrical is not my strong suit.

Thanks

Yes, the tan wire is the one. (I think mine was tan, too). I do not believe you need to remove anything from the panel, just ensure your coyote pigtail wire is the one providing power for the fuel pump circuit so it controls it.

Looks like your harness is the same as mine. Don't cut the wire too close to the end. If you cut it in the middle you can use the fuse for seat heaters or something else.

Thanks guy. Ducky thanks for the picture! Extremely helpful.

DON'T cut the short wire. That feeds your inertia switch.... The switch that kills your fuel circuit if you have an accident/roll over.

You're getting good feedback but just a bit more explanation so (hopefully...) it makes sense. The fuel pump relay in the RF panel is to enable the inertia switch. The ground wire for the relay goes through the inertia switch. Closed = complete circuit and relay operational. Open (e.g. inertia switch tripped) = no ground so relay cannot be energized and fuel pump cannot receive power. The RF panel provides +12V to the coil side of the relay as well as the input to the switched side of the relay that goes to the pump when the relay is closed.

In earlier versions of the RF panel (like yours) both +12V relay coil and fuel pump power came from the same RF panel source. In later versions of the panel, starting several years ago, RF split the +12V feed to two different sources on the panel. That's the version Factory Five shows in their current instructions. They show cutting the short wire which is the feed to the coil side of the relay and attaching the Coyote fuel pump wire to it. When the Coyote system sends +12V on the fuel pump wire it closes the relay on the RF panel but the fuel pump itself is still powered by the RF panel. Personally, I don't care for this approach. It means you have two separate harnesses associated with the fuel pump circuit including two fuses in two locations. If you cut the large wire that Ducky2009 shows and attach your Coyote fuel pump wire there, the Coyote system will power both the relay coil and the fuel pump itself. You can remove the RF fuel pump fuse because it's no longer in the circuit. That's how I've wired both of my Coyote builds.

Hope that helps and isn't too confusing.

I did what Ducky did in his picture. Do I need to remove the fuel pump fuse from the fuse panel? Also, maybe you can help with this. For some back story my engine was wired for a 1997 mustang cobra engine that turned out to be a big mistake. Also, I was lucky enough that over the winter a mouse got into my wiring and ate all the tags off the RF harness. In the Factory five instructions it asks to locate the EFI crank and coil wires from the chassis harness. I easily found the orange EFI wire that says crank or EFI. The blue wire not so easy. Is it one of the blue wires coming from the ignition switch according the wiring diagram? EFI crank power? If so do I use that to connect to the coyote starter wire?

If you wire like Ducky and I described, you can remove the RF fuel pump fuse. It's not hurting anything. But also not doing anything. The Coyote pigtail Light Green Ignition Relay Trigger goes to any RF ignition controlled +12V source. The RF orange EFI/coil wire is the most common. The Coyote pigtail Light Blue Starter Motor Request (SMR) goes to the RF blue crank wire from the ignition switch start terminal. The large Coyote starter wire goes to the small binding post on the starter. +12V battery power on the large starter binding post.

You do have both the Factory Five and Ford Performance instructions, right? It's all shown between the two.

I do have both. Just making sure I don’t screw things up. As always appreciate the help from you and the forum.

that's a cool idea - one less fuse to worry about!
