Under the dash on a 2 dr where can I find both constant and switched 12v power that I can tap off of?

Cigarette Lighter.

use a toggle switch for the switchable power

I know that much B) but where can I find power that is switchable (through the ignition) ?

isn't there switched power to the head unit? what are you trying to run with it? You might be better off using constant power and the remote/ant wire with a relay for anything big

You can find both in the fuse box...Thats where I connect my FM modulator for my Mp3 player.

I don't know what you are trying to hook up but to avoid any Wiring messups I would suggest just running new wire with fuse from battery to switch then to whatever you need it for weather it be fog lights or under body kit. :thumbsup: And don't forget get Grounding it

if your looking for something that has power when the key is on and is under the dash, i just tied into a wire off the heater controls.

ignition driver side fuse, constant passenger side.
