351w Correct Wiring
Hi,
I bought a Ford F1 with a 351w installed, I believe from a '72 LTD. However the wiring throughout the truck is awful, 5 different pieces of wire with 4 connectors, to connect the Alternator to the battery, etc. Therefore I have decided to re-wire the truck and engine. I have been looking for a good wiring diagram for this engine but have not found one. Therefore I hoped someone could point me in the right direction or give advice? Please note the engine has an electric fuel pump rather than the original mechanical one, which has been capped off.
Below is a diagram of the current wiring:
Any feedback/advice would be greatly appreciated?
Thanks Richard

Hello Richard,
Your diagram seems correct. Keep in mind when you go to set up the 351w that the firing order is different than it is for other small blocks...I think they also used a different #1 cylinder as well. I may be getting ahead of you, but I figured you'd eventually get to the spark plug wires while you're wiring the engine area.
Also....depending on what alternator you use...the wire that comes from the ignition switch to energize the voltage regulator is attached to the coil + lead...that is correct. Note that some alternators once energized, will feed some power back to the system. When the key is turned off, the alternator keeps power on the line and the engine doesn't shut off. The fix is a diode in that line. This doesn't apply to all alternators...but apparently many of the single wire units.
