Idle up switch

I have been reading past threads about adding a idle up switch to our tundras. I was winching some large 30-50ft trees out of a ditch for firewood and my battery couldn’t keep up without cutting power to interior devices. (Yes my battery needs to be replaced. It’s still the factory OEM) increasing the RPMs to 1k was my work around for about 4 hours worth of tree removal. Since then I have ordered a Northstar 27F AGM battery that should be arriving this weekend. I know this will solve my issues, but having a dedicated switch would still be nice. Any ideas on how to do this? I saw a thread that someone put a 10k resistor in-line with the thermostat causing the truck to idle higher..

 

There is also a fuse that increases alt output. Not sure if that will help or not.

I had a manual throttle lock for the accelerator pedal that I used during airing up the tires to keep the air compressor happy at all times and I miss that with that Tundra. I can sit inside and watch the sensors on the dash while the air up/down system is working and I can push the accelerator but not the same.

This would be a great mod for the Tundra

 

I used a Chevy diode to increase voltage for my northstar 27f. $3.00 mod I found on this forum.
