I am an A&P/IA, when I built mine I used a standard continuous duty solenoid mounted on the back of the cockpit just like on a certified aircraft, pax side, just above the battery with a switch in the OH panel. From here it goes to the main bus for the overhead as well as the main forward avionics bus for the pedestal, the starter wire is also attached to the cold side of the solenoid so that if the master is off, no chance of the starter moving the blades in the shop.

Wiring is easy- the positive goes from a ring terminal on the hot side to one terminal on the solenoid, the other small terminal goes to a toggle overhead that then connects to ground. The switch connects the circuit to ground thus energizing the solenoid.
