I’ve had the same exact USB port on the shelf for months. Since then I remembered a double adapter I simply plug into the cig socket. The problem I really want to overcome is no power there unless the key in ON. Did you set it up to be an always hot power outlet?
Baldi, I set it up that's there's power only when key is on, used the original wires for cig lighter.
I cut the plastic L shape double cig lighter connector in half with wire cutters and just plugged em into the blue sea + and -
workes like a charm
I cut this in half in pic...original wires so I could just plug in
