Tech question re splitting 12v to 5v hardwire
In making a plan to add power supplies for a GPS and phone, a couple of questions came up:
1. I bought the OE two wire horn connector and plugged it into the grip heater connector in the wire harness. I plan to connect a GA-NHWC2 hardwire 12v to 5v set up with a usb micro connector at the end. This will power the GPS. I would also like to have power for my smart phone. Should I splice in a usb mini male plug after the "black box" on the GA-NHWC2 cable? Or would it be better to get a GA-NHWC3 cable (same as the GA-NHWC2,except ends in a usb micro plug instead of a mini plug) and wire them both to the end of the horn connector?
2. However I connect the mini and micro cables to the end of the grip heater/horn connector set up, is it a good practice to make the connection at the end of the horn connector black plastic plug with two male quick disconnects? Or is it way better to clip the black connector off and solder the connection instead?
3. In testing the end of the horn connector last night to find and mark the hotwire, I accidentally made enough contact with the engine to make a small spark. I was under the impression the orange/green wire in the grip heater connector was fuse protected, yet the fuse did not blow. Should I add another fuse between the grip heater connector and the 12v to 5v converter cable?
Thanks for any helpful replies.
