Good deal with the usb but have had plenty of issues trying to get all of my active target devices wired and still like doing a separate front source with the lithium supplies coming in tomorrow I hope… take care
Did you wire it in directly to your shutoff switch or do you run it to a bus board first, then going to the switch in case you need to install more electrical stuff later? Not sure how all that worked. The only 1 I've ever installed was at the dash & i just wired it directly into the ignition so it only worked when the key was on.
