Re: Need help finding switched power source
Most of the existing circuits are fused and wired according to the current that they already are drawing plus a little extra to keep from blowing fuses all of the time. If your new accessory is going to only draw up to an amp or 2 I would feel safe using any existing circuit. You should be able to use a meter to find a wire that is hot only in the ACC/ON/RUN positions. The 12 volt outlet in the front console compartment below the HVAC controls is switched with the key. The one in the armrest center console, on the other hand, is always on.
