Starting system wiring
1.........ECU is wrong in at least two ways. A--ballast wiring wrong. B....Connector is drawn poorly and impossible to tell if wiring to ECU is correctly represented
(Keep in mind that ballast wiring is exactly the same for either breaker points or ECU)
Here is fair representation of ECU wiring EXCEPT FOR !!!!
Wire at top right marked "start" IS WRONG!!! This wire goes to IGN2 on the ignition switch. The "S" and the IGN2 work the same except they are SEPARATE switch contacts in the ignition switch, to prevent backfeed in those two circuits!!!!
The wire at bottom right marked "run" goes to IGN1 on your ign switch
2....Terminal marked IGN on start relay goes one place only--to the S terminal on the ignition switch
3....Starter to relay to battery was that way on some vehicles but is inferior. It is better to run a big cable direct from battery to starter, and some sort of branch cable to the starter relay, which can be smaller IE no4 or maybe no6. You can run that back from the starter to the relay EG
4...Since you show a volt gage and not ammeter, you can run the "one wire" direct to battery with an oversize wire, DEPENDING on alternator output. If it is 100A or so, I'd use no4 wire. ONe wire alternators MUST have larger wire than with an exciter / sensing wire/ external VR because the only cable IS THE sensing wire
