I'm using 22 Gauge Wire - is that what gauge T Splice I should get? I'm not sure what gauge wire runs to the fuse box.

It's somewhere between 18 and 20 gauge I believe. The tap splices are usually good for a range, so if you can get 22 to 18 gauge ones you'll be fine.

For the no voltage on the switch, measure the red wire to ground (with the ignition on). If that is still zero, then disconnect it from the switch and measure the red wire separately to ground. If it is still zero, than your ECM pin is not properly seated.
