Auto Meter Cobalt 3351 Installation

Because of the mechanical design of this gauge, installation of a wired temp sender is not required. However, this gauge comes with a 8 capillary tube with a 1/2″ NPT mounting nut that can be installed in your transmission pan, transmission line, or transmission pressure port.

While there is no electric sensor wiring, you would still need to wire in a ground and 12 volt lighting to illuminate the gauge.  This is common with all mechanical Auto Meter gauges.

No matter how you plan to install this gauge, you still need to find a mounting location inside the cabin of your vehicle.  Depending on your application, you might be able to utilize a gauge pod specific for your vehicle that mounts on the A pillar, or a universal gauge mount would be fine.
