Finally got my switches installed. Does anyone know how to wire up my electric fan so that i can turn it on and off... seems to be kicking out on it's own and i want to chose when its on or not.

 

same concept, instead of it going to lights it goes to your fan.

from the battery run 2 seperate wires, one to the #30 prong on the relay and one to your switch. it looks like you have light up switchs so run power to your switch from the accesory slot on your fuse box. that way it will only work when the car is on.

 

looks good, alot cleaner than the regular rockers. And i've noticed that area b4 and wondered why i didnt use it to begin with? lol

 

i would make it so it can come on and off as it pleases. Then run a second power wire to it so you can turn it on when you want.

that way if you step out of your jeep, the electric fan will turn on and off by itself, and it wont overheat cause you are not babysitting it

 

Like Mattpar said, its nice to have it still function as normal, as well as being able to turn it on when you want it.

As far as wiring it...
There's a blue/pink wire that goes into your PCM, that controls the fan. Basically, you just need to use a splice connector(or any way to splice) and splice into that wire. Run that new wire back to a switch. Instead of running the other part of the switch to a power source like you would with foglights, it needs to be grounded.
There is a pretty good thread on JeepForum with more info.

Seems like quite a few 97+ get CEL's from doing this. I just did it not too long ago with a 99, without a CEL... although mine is ran through my relay box, not sure if that has anything to do with it.
