Alright! 30 min and a T-Tap later. So the plan is to use the 110 outlet that my Custom 2500 doesn't have. (note the wires are there if you do want it) You just need to add an invert to the batter and wire it in. This is only for Power, not connecting a 2nd USB to your radio system.
So I pulled out the cigarette lighter & the panel for the 110 outlet.
I don't have a soldering iron, so I opted for a T-Tap
My plan was just to replace the spacer with the USB port I bought. However, the USB adapter I bought is wide enough but not tall enough. So I opted to use the spacer as a backplate. I used a hole saw just bigger in diameter than the USB port and drilled through it.
Shoved everything back inside to hide the wires.... err um cable management
And voila... USB ports for the copilot and I can still use my dash camera with the cigarette lighter. (that will be the next wiring project.
