Looking for the best power source to run an AEM wideband o2 sensor? I'm assuming the key switch is not the right spot. Any help would be appreciated.
you can pull it off the hot lead to the accessory outlet if you do not run with anything plugged in and its easily accessable.

langow - Buy a 30 AMP Relay, an inline single fusebox with a 30 AMP fuse or smaller (at least 10 AMP). Connect a wire from the red/white wire at the ignition key to the trigger connector on the Relay, this wire will trigger the relay to open. Then ground the relay. Connect a wire from the battery to the relay, connect a wire from the relay to the WBO2 unit.
You will have power to the unit only when the ignition is in the ON position. Wired this way you will not overload the stock system and fuses.
