You have 2 wires going to the + side of the coil. One directly from the ignition switch that is hos in "start" only. The other wires comes from the ignition switch in "run" position only and goes through the resister and then to the coil.

The problem is it has a 4 wire main connection and a 2 wire connection for the fan how can I wire the 2 fan wires into the main coil plug with 4 wires

What do fans have to do with a coil? I have no idea what you are trying to do.

It has to do with the fact that the electric fan has 2 power wires attached to it that attach to heater coil or resistor for blower and the new resistors do not support the extra 2 wire plug from fan to resistor they just support the ignition wires and switch

Then you simply have the wrong resister and you need to get the correct one.
The heater CORE is a metal housing that contains coolant. It has nothing electrical.

You can wish it will work forever. That isn't going to make the wrong part work. Unless you find the correct part, you have no blower.

What I'm guessing here is that you have auto temp control which uses a module and not a resister and you're trying to make a resister work in a system that doesn't use one.
