It has both power and ground wire connections, The ground goes to the temp sensor (from the kit) mounted on the engine. The power goes to a spare fuse location in the fuse box.

OK, now I know what you have ...
The GRD wire goes to a sensor before being grounded on the choke housing and/or intake manifold? The KIT included and instructed you to put it (if the same) after the choke thermostat? Need a photo ...
As for the GRD wire becoming hot, it may be the way it is wired causing partial GRD or the choke thermostat overheating due to lack of proper ventilation and the wire acting as a heat sink..
Being off a 65/ engine, the choke mechanism will be different in design as opposed to the 61.
