I am trying to install a 12v outlet just not sure if i can attach the wires to my ac terminal.
Any ideas to where would be best.

Depends on what you want to run. If you go downstream of the ignition switch you end up with 11 volts during an idle. If that is fine, then no problem. But for me, I installed a relay off the ignition with a direct battery feed. That way my accessories get full battery voltage even at idle. Easier on the ignition switch for current as well. Good idea if you are going to run something most of the time.

Not that you do not know, but the way a relay works is that the ignition power is used to switch the relay on and that is a low current load on the ignition circuit. Then the relay that is now switched on provided a direct battery feed to your accessory. I found my USB accessories wanted a full 12 volts all the time to charge the phone. So a relay was the easy way to do that. And I also moved things like the electronic ignition to the same relay as they like clean higher voltage power as well.

I assume this is to run something like a cellphone charger? I would (and have) run it through the running light circuit. That way it is off when the key is off but on whenever the key is on.
