dunno if the link works or if you hae to enter the vehilce info yourself
if it is a swap engine pick a 77 f250 4x4 and then select engine wiring


there is an entire troubleshooting guide for durasparks that is very good
with a DVOM and an old analog meter you can test every component
I used it to diagnose a dead distributor pickup
