This is the wiring diagram I used. Thanks to Tom S. for the diagram.
For the ignition key source, I used an unused terminal on the glow plug solenoid.
For the starter trigger wire, I came off the starter solenoid and ran the wire across the top of the motor and down to the oil pressure switch. This allowed me to put all the wiring in wire loom to make it nice and tidy.
For power, I used a wire terminal and connected it to where the main power wire connects to the under hood fuse block. Then I put a 20A MAXI fuse in the power wire going to the relay.
Power for the pump was ran down the frame rail and to the pump power terminal.
Ground was acquired for the relay at a factory ground location on the inner fender on the driver side.
Ground for the pump was put to a bolt for the fuel filter base mounted to the factory frame.
I still haven't got an inertia switch in the wiring yet, but will as soon as I get one out of a wrecked Ford.
I had to use a 1/8" close nipple and a 1/8" coupling to space the fuel pressure switch out so it didn't hit the oil cooler when installed.
The wiring is literately the EASIEST part of the whole install.
I was completely shocked when the truck fired up with no problems. It started faster the first time after the install faster than it ever did with the mechanical fuel pump.
The fuel pressure regulator was set at a factory setting of 45 PSI
. Once I got it adjusted to 70 PSI
it idled and ran smoother than before.
