1. Is this the correct starter relay?
It is stamped D2AF-11450-AA.
2. How do I know which post with the heavy duty wire goes to the + side of the battery and which post is attached to the heavy duty wire from the starter motor
3. I assume that the smaller studs connect in the same way as they do on the wiring diagram provided by wwag.com.
a. Heavy duty wire to battery positive. Small stud next to it goes to ignition switch.
b. Heavy duty wire from starter motor. Small stud next to it goes to starter button switch.
Battery terminal is the left large, starter is the right large.
Starter switch left small.
Must ground through the bracket.
To back up a little, I assume you are adding electric start to the pan so are not staying period correct?
I would use a much better relay than that and doesn't use so much current. That way it is much easier on the switch.
I use a on my shovel.
On this one you need a ground to the second small terminal.
If you don't like that one at least use the flat style Ford relay
Same relay as the one you have but better mounting.
Ford uses these heavy relays as they are the solenoid and have the entire starter amp draw through this relay.
On Harleys we only energize the true solenoid. No starter current through these on a Harley.

...and you are correct Mark, I am adding the cannonball e-start to this project.
Early on (#10-16) I posted upon the starter unit. John stated he used the heavy duty Ford component. Just clarifying that I am getting the correct one.
