1992 Dodge Ram Van B250 318. When I put the heater switch on high with the AC on the wire from the main splice under the hood to the ignition switch heats up and if I let it run will eventually melt the insulation and then burn through the wire. My guess is that it's drawing too much current but I can't figure out why. Any thoughts?

When you say "heater switch", I assume you are talking about blower motor?
If that is the case it sounds like the blower motor is drawing too many amps. You would want to start with measuring the amp draw of the blower motor. You may also want to check the fuse box and make sure all slots have the correct rating fuse and larger fuses aren't being used. It really seems like this should pop a fuse before melting wires...
You might also want to check the draw on your a/c clutch
