Finally got in touch with SwitchPros directly. Need a sanity check on what they told me.
So, I have the blue wire tapped into A/C fuse under the dash. Based on what they've said above, that does not provide sufficient power. Ideas on where to move it? I do not have a 12v outlet on my dash.
When you say A/C is the fuse labeled "A/C IG" or something similar? If so I'd move it to another location as that's the fuse for electrical components related to the air conditioning system. Information on the web is a little scarce but I think your underdash fuse panel is organized like this:
If you have a multimeter you can probe for a fuse position that only receives power when the key is in the ACC position. If you don't have a meter I'd try one of the following:
15A CIG (1st position, right column)
7.5 ACC (3rd position, right column)
7.5 PANEL (4th position, right column)
15A PWR OUTLET (10th position, left column)
I'd probably start with the 7.5A ACC position...I'm assuming, based on other Toyota vehicles, that this is the fuse for all the interior accessories (radio, navigation system, rear view entertainment, rear view mirror and some trailer light connections). Power to this circuit will come on when the key is turned to the ACC position (or if you push the start button without your foot on the brake if it's a push start vehicle) and then remain on when the vehicle is running. Power continues to flow through this circuit once the vehicle is turned off until you open a door, that signals the vehicle to cut power to this circuit.
The 7.5 PANEL fuse would be my next choice, but there's a slim chance this is a constant power circuit with relays controlling idividual components on this circuit.
The CIG and PWR OUTLET fuses may be constant power to, not sure how they work in the Tundra. If you tap those locations and the switches work without the key in the ignition (after accessory power has turned off) then they're constantly powered and you'll want to pick another location.
