I don't often say this about the Haynes manual but the Haynes manual for the 620 has all years of wiring diagrams. The '77-'79 are near the back pages and quite detailed and direct copies of the Nissan FSMs. New are only $20? Probably less on e-Bay then you have a hard permanent copy including info on the front clip brakes,  ball joint suspension and steering, EI distributor and internally regulated alternator..

 

You have a goat??

Haynes 28022 (277) US... there's 10 double pages of wiring diagrams. The electrical is the only reason I have it the rest is much too compressed to cover '73-'79 so I have a '73 and a '78 FSM.

Electric ignition ? thats a no brainer now to do and use existing wires

Changing the ball joints and disc brakes doesn't involve any wiring. Only thing is the EI distributor. Just tie the two wires from the ignition switch together to power it. Easypeasy
