need a wire to pick from

Going to add a pyrometer to my 06 ram and need to know where to pick up the power for the gauge and the light would like the light to adjust with the dash lights. any help as to where to pick up the power from? 06 3500 diesel

Was looking for one last year myself when adding trans/diff tem gauges to the Durango. Being a lazy guy, I used one of those blade-type fuse power taps on an unused fuse slot in the fuse box on the driver's side of the dash. The box that's accessible only when the driver's door's open. Prodded around with multi-meter to find one that that was only on with the key on. Ran the resulting power wire up the door jamb trim to the dash-mounted pod, wires for the probes down the same route and through the firewall left and below the column.

I know it's not the same body/year, but it's an idea.

anyone have an idea as to where the fuse box is on my ram? is it behind the secret panel on the drivers side of the dash just trying to get info before i actually go out and tear into it lol

you will have to find a wire coming from the dimmer switch or from one of the dash lights.
