My PDM60 came in the mail yesterday (Wow! Ordered it the day before). This will definitely supply the correct power as it is hard wired directly to the battery and then uses the aux power wire as a switch. It enables you to run 6 devices at 5-20 amps depending on which circuit you use. At this point, the only thing I will be hooking up is the dash cam and probably an outlet for the radar detector.
Speaking of dash cams....I had a heck of a time finding a spot to mount the rear camera. I ordered about 10 different goPro mounts and one of them will work. It's near perfect but could use some modification so I am going to have my shop at work make me exactly what I need. It's very handy to work for a factory where we have several fabrication experts
