Want to hardwire Sirius in '05

[sixfootpeter]

I am trying to hardwire my Sirius in my '05 with the SIR-PVK1. The problem I have is that I do not know where to tap into the vehicle's power. I want to go with accessory power so that it turns off when the vehicle is shut off. I drive an '03 Impala that has a power drop (extra power wiring for accessories) right behind the glove box. Does anyone know if the Explorer has something like this? If not, any ideas on which wire it would be? I seem to have no luck finding the '05 wiring colors and codes, but find every other year. Please help. Thank you.
