Hey guys, I'm starting a little project here and would love if someone with more wiring knowledge than myself could look this over and tell me if everything looks correct. The goal is to replace the stock power socket beneath the stereo with a fixed USB panel mount with two USB charging ports. (I know this is kind of a frivolous project, just doing it for the hell of it) Previously, I changed the wiring of the stock power socket to be fed by the constant 12V power instead of the accessory power so the socket is powered even when the car is off. Here are the two products I intend to use for this project: USB Panel mount 12V to 5V Converter And here is a diagram I drew of how I planned to wire these into my car: I am going to cut off the male USB plugs and remove the insulation to reveal the 4 wires inside each cable each containing a positive and negative wire to power the ports, and a positive and negative data wire which I will connect together to cause a short (which I understand should allow for faster charging since these ports will not be used for data) I'd greatly appreciate if someone could look this over for any potential issues, I think I researched it properly and it seems like it should work. My biggest questions/concerns are: 1.) Do I have the right idea as far as shorting the data wires together? 2.) Can I wire the both the positive and negative wire from each port to the same 12V to 5V converter output wire, or do I need two of the converters and need to keep for instance the positive from USB port #1 separate from the positive from USB port #2? I'm fairly confident about everything else, but question #2 above in bold is my primary concern and uncertainty. Any input would be greatly appreciated!
