I am a big temperature guy, and I always want my stuff running colder than the stock temperature. I was thinking about installing a manual switch inline with the automatic system, so I can manual switch on and off the fan and still retain the stock fan control. Any thoughts from you guys?

 

I wouldn't wire that like that.

I would run a relay.

 

relay, fuse, load-sensing timer so it turns off when the engine isn't running. at the very least.
or do an inline thermostat mod, drop in a 180, and switch to an electric fan setup. all are well documented on this forum, and all seem to be very effective.

 

I ran power off a relay in parallel with a switch on the dash. The intent was to provide some extra cooling while in the trails. I have the 180 stat and the aux fan only made a couple of degrees difference.

 

Simply turn on the A/C.

 

Sorry to steal this thread but does anyone have any good resources for learning basic electronics that can help with wiring in things like LED bars, switches, etc...

Thanks!
