Spoke with Tech Support at PowerMaster. They included a diagram that I thought was interesting and I wanted to know what they suggested for wiring up this starter as I've never ran a mini torque starter before. They suggest #2 wire on their diagram, but said #4 gauge probably is fine. I checked at O'Reilly and #4 is likely what I have. I may look back at my receipts and see if I can verify, but that's about all they sell.
I'm attaching a link to the diagram, but they say using a Ford Style Relay/Solenoid helps at times with these, but the wiring is different than the normal 'Hot Start' wiring because there is no jumper on the starter and the solenoid is wired different as well. Basically, from the Battery to the terminal on relay, then from this same terminal to starter. Then from the ign switch to the S terminal on relay and on the other large terminal #12 gauge wire to the S terminal on the starter.
While I'm not 100% sold I need a heavier gauge wire, I asked for input and it seems everyone is saying go bigger, so I'll heed the advise and I'm looking at #2 gauge wire, lugs and battery terminal ends. Any thoughts on these?

Here's a link to the starter wiring.
