I have to disagree with you on the last half of that. I say it makes no difference when you power that large wire, it will work exactly the same way as wiring it normally. It could be on its own switch if you want, turn 1 key energize the solenoid, turn the other, fire the windings. Or vice versa, the motor gets power first and then energize the solenoid wich will switch the motor windings when it is needed. Either way, there is no current passing through the motor windings until the solenoid pulls in and completes the cicuit. So, if we power both at the same time, well, the solenoid still has to travel that inch meanwhile the windings will have power sitting there waiting for the big moment as usual. Agree??
Not that I would wire it like that myself, you are just adding something else that is pointless and could fail. But if the wiring is all in place already, it would be alot less work to use the relay, join those 2 starter terminals, and run the big wire to the starter.
As for what size fuse to run. Not sure I totally agree that 30amps is needed but my yougest son is asleep 2 feet away and i dont want to turn the light on to find my manuals to look up what most cars use. So i will leave that one alone as 30 amps would work either way, and I could be wrong.
Please tell me if this doesnt make sense and I am totally leading everyone astray.
