what would i have to do
what would I have to do to run 2 12 inch electric fans pulling 25 amps a piece?, I fried my fusible link and trashed my fans, looking to do it right this time round

Welcome To The fan Club
You should give each fan it’s own circuit on the power side.
For each fan use 10 AWG wire in the power circuit protected with a 14 AWG fusible link.
Have the aforementioned connected directly to the battery.
To keep your new setup looking good you can install a junction terminal which can be used to connect new circuits.
The triggering part of the relay-to-sensor circuits can remain stock.
It’s up to you if you want both fans to come on at the same time, or first one, then the other.

Re: what would i have to do
Wow....25 amps apiece is a lot of power for 12" fans IMO. That really taxes the normal 30A relays as far as max capacity. If you plan to run them fans @ 100% speed every time they're on, I'd suggest using 40A diode suppressed relays.
