Question is - what you tapped - what is the existing draw on what you tapped? What else is on it? Will it possibly blow a fuse when you have everything on?
On mine, I tapped 2 seat heaters to that dash 12v, and I threw caution to the wind due to convenience of being tied to the key, I have my Bully Dog tuner power on that same fuse, and even had my arb compressor on/off switch tapped to that. The arm would blow the fuse every now and then if I had the seat heaters on and threw the switch. That one ended up getting re-routed elsewhere.
**I'd note I don't use that 12v to charge my phone or anything....so the port itself not drawing anything.
