Used position #5 fuse and that ground torx. I did NOT pull off the A-pillar and all. I simply pulled back the rubber door gasket and tucked the wires up under that door seal.
Make sure you use a switched +12v source for your detector. Use a volt meter to confirm the power source before you button up everything.
