I ended up using the plug for the clock to power the switch. It has a 12V+ that is active when the key is in ACC position.

I was searching for somewhere to plug in the temp sensor from summit and saw this picture in a post on pirate:

The thermostat housing I have now doesn't have that sensor that is circled in red. What I want to know where I could find a t-stat housing like that, or a part number? I'd feel alot more comfortable with a housing that was made to have a sensor in it than drilling/tapping the existing one, it's a little thin.
