I used positaps as well, connected to the rear running ligh circuit, though I use all LED lights, so there’s a good bit of overhead light circuits on my bike.
One of these days I’ll rip out all the wiring and redo the harness to actually take full advantage of my PDM60.
While we’re on the topic of electricity, just picked up the attached for my car. It’s the only 12V to lightning power source I’ve found yet that actually fast charges the phone. Nice because an IPhone + sized phone with screen on running GPS, BT streaming music will “barely” charge from a 1/2 amp usb plug with all that running.
