    switched 12v for oil temp gauge

    I've got a 3 gauge cluster I'm going to mount in place of the ashtray. What is a good switched 12v source for this gauge around the center console? Thanks.

          Aux fuse panel in the engine bay is pre-wired with one constant and one switched 12v pin, I used that and a fuse, route the wires through the grommet in the firewall there.

            Correct.

            I used a switched 12v under the dash for my V1 and map lights. Just get a multimeter and find it.
