Having a DBL throw switch that could interrupt/override the circuit would be all that would be needed. One way turns it off for water crossing so you dont crack a blade and pull the other way to turn it on for an extended period of time. You could take that a step further by wiring up a latching relay and a 555 timer so that when the key turned off, it would latch a relay open/closed, depending on your circuit tastes, and then the 555 timer I think can run for up to 2:45 (2 mins, 45 secs), and then auto shut off.. THE poor mans turbo timer function essentially.

As for the Trans cooling.. You could extremely benefit from removing the Autotrans cooling from the internal radiator and go to an external solution. This would prevent SMOD (just google Nissan SMOD) preventing a future catastrophe, and by adding an external cooling source you can not only increase cooling efficiency with a larger surface area but in some cases use a smaller fan, far less power used, think of it as upgrading your current radiator to a 3 core, then adding dual 10" fans, all while adding in a low temp thermostat too.

Just a product consideration or a jumping off point;

All in all, between many upgrades, Radiator core size, fluid types, internal vs external cooling components, single/multiple E-Fans there are a gaggle of metrics to consider depending on what you're looking for in the end.

Not sure where you live, but our Ranger rig's cooling/electrical systems had to be upgraded. Mostly due to strain/over working condition concerns, being out in the desert or dozens of miles away from civilization if you will.

In summer here in Vegas, average ambient temps are around 115*+. Throw in slow speeds in low gears, and up/down hills, A/C on some times or a considered metric of just being able to. We wanted to make sure nothing had a choke point for more than simple reliability, more like Non-failure demands. We are fortunate enough to have a manual trans, although the thought of a an external pump and cooler was brought up by our team, I think we may tap the trans for a trans-temp meter before that comes to fruition.
