I took a feed off the back of the heated rear window switch for a 12v socket with usb ports. Ran an 10amp inline fuse as well. Works great and switches on with ignition

It comes down to his much you want to pull from the 12v.

From the fuse box or the solinoid are good points.

I'd splice into the 2nd point of the ignition wire with an in-line fuse, then go from there, that way it will all shut off when you take out the key.

Personally. I took a permanent live from the starter solenoid. This is switched via a relay which is triggered from the ignition first "accessory" click. Taken from the protected side of the fuse board. Now i have a fuseboard just for my junk. So far ive put my CB radio on it.

I took a feed directly from the battery and put a relay in fed from a switched live.

Should be fine on the "accessory" circuit - ignition position 1 for heater fan and radio. Wiring off the solenoid isn't necessary, but a good idea if you end up wanting to add more - use decent sized cable.
