I've been using them for a long time. They haven't worked well, take forever to heat up. You need to use that little resistor thing called the choke control. The power wire plugs into the choke control and the choke control plugs into the choke wire. I'm sure it will work like Chrysler intended then. That Tomco one doesn't have the wire but the factory ones and the Carter ones do. The part number for the choke control is 3755770. The early mechanical TQ chokes that used a gasket below the well cup always seemed to work better for me.
