Usually you have to splice the wires into the old plug.
You might be able to find a diagram on the websites for auto parts stores such as autozone.

Check where the wires go into the blower housing. There is usually what appears to be a small plate held by 1 or 2 screws that the wires plug into. This is the speed control resistor. If it's going bad, it will cause the problem you describe.

Either something was mis-wired, or you have a shorted blower motor or a cut in the wire insulation that is shorting to ground. I'm amazed that a 40 Amp fuse is used for the blower motor - that is a lot of current for a motor that size. (13.6 Volts times 40 Amps is 544 Watts for a fan?! There must be some other stuff on that circuit or somebody put in an oversized fuse.)

you need a temp limited switch and for the most part its close to the blower motor has a small screw on each side with a plug in the middle give these websites a try www.autozone.com and www.alldatadiy.com if all fails stop by your Jeep dealership in the parts department and they be able to show you what i am talking about and print you off pictures and diagrams showing you where it is located wish you the best of luck Michigan Man.

most likely the blower motor try tapping it if it makes a noise or starts blowing a replacement is necessary

I hope help you with this (rated this help) Good luck.

Blower motor resistors are found on the pasenger side ducts near the blower motor. It should have three wires going to it.

It might be beneficial to you to go to a scrapyard and take a look at one that hasn't been chopped up! You may even want to buy whatever has been removed while you are there!
