Get your dash power from the Batt cable at the starter.....like chevrolet does
Origionally he was going to run a top starter, and it would have been good to go, don't make him redo it

He's so close....

The way he has it now is how Mercriuser, Marine Power, Indmar, Volvo Penta, among others do it, why reinvent the wheel?

Besides, troubleshooting with that solenoid is easy, because you can hear it pull in from the dash
