Electric Fan

Does anyone know how to wireup the second electric fan so it will run all the time when off roading and i can switch it back to normal when driving it on the road. because I know the new cherokees have a nick about changing stuff like that they tend to throw CEL

There is a writeup about it on projectxj.com, or if you use the search function you will find a long thread about it that I started while doing the same mod about a week ago.

I dont think that will work.. I tryed wiring it a differnt way but if you even unplug the electric fan and wire it up to the battery it will throw a CEL.
