Yes...as per the above drawing...the signal from the A/C or in-cab switch simply energizes the coil of the relay. Relay's draw next to no current so you don't need to worry too much about the wire size there.
The actual wiring which passes through the relays to the fan motors needs to be substantial enough to carry about 50Amps. Also...make sure the relays are rated at same (or higher).

Do you have tuning software Chad?
First thing I'd do is lift the rev's at idle just to see if that's the issue.
If that doesn't help...atleast you'll know to look elsewhere for the issue.

Now I need to test this at night with all the lights on and see what happens.
Thanks.
