Hi Brian,
I can't think of a reason you would need a diode with a relay. Just
hook it up like you see used on a car and starter. With a push button
hot triggering the solenoid.

Hi Brian,
Why don't you use a regular car starter solenoid. Or four of them
like Warn.

If you have any electonics near a relay coil, is good idea to use a
diode or even better a diode and resistor to get rid of the inductive
kick that can literally punch holes in solid state devices.
Those need a bit of current and high voltage to deal with the kick.

Some folks idiot proof connections with diodes... kinda like the phone
sets that work no matter whether tip and ring are reversed or not.
