I want to hardwire my magellan roadmate 1200 gps into my dash (I have a 2000 Pontiac Trans Am M6), and the plate covering the tcs switch readily comes off, so I was thinking about tapping into the power wire and ground for the switch to the power cord of of my navi. I have two problems, I am not entirely certain which is the power and ground wires (I am guessing the red is power and the black wire with the white stripe is ground), and I also don't know what the current rating is for the tcs switch power (is it enough?). I was thinking about using something like this:

And then putting a small hole in the plate for the connector to peek out. Any thoughts?
hardwiring gps to tcs switch?
