Derale manufacturers remote transmission coolers that do have two wires, however, the Derale Series 8000 Transmission Cooler # D13504 that you reference does not have any wires.

If you do have an aftermarket remote transmission cooler - there are two types of hook-ups: coolers with a thermostat only and those with the option of either a thermostat or manual switch. The hook-up directions are as follows:

In the Derale # D15830, the positive wire attaches to a 12 volt source such as a manual switch or thermostat and the negative wire attached to a good ground chassis.

The other is the Derale # D15900 where the positive wire attached directly to the thermostat and the negative wire attaches to a good ground chassis.

If you have a factory transmission cooler, you will have to contact Dodge for further information.
