Ok assuming you don't have air conditioning and it's just the cooling fan you're dealing with, and not the condenser fan.
The wires should be like this:
The cooling fan relay is supposed to have power on a blk/wht wire from the dash fuse box when the key is in the "start" or "run" position, the (10a) fuse that's supposed to supply this power is called "engine fuse". The relay should also have power at all times on the wht/blk wire, which comes from the "btn fuse" (30a) in the engine compartment. A good test light is a must for this kind of testing, I also find a meter is very valuable as well.
Once you establish or re-establish these power sources, you will probably be able to figure out where the relay should be located, probably by tracing that wht/blk wire right to it from that under hood fuse box. That relay should be in the group of three relays, just behind the battery, probably the one closest to the shock tower.
Now the way this relay gets it's signal to operate, is the ecm supplies a ground to it on the brown wire.
The ecm of course getting it's que from a temp sensor. At that point the relay opperates and sends power through onto the yel wire which then goes right to the cooling fan motor. The way the temp sensor works is, it does nothing when the car is cold, but when the car reaches a certain temp, the sensor then supplies ground to the ecm. When everything is funtioning correctly, pulling the wire off of this sensor and simply touching it to ground will opperate the fan. Now knowing this, you have to consider that if this sensor is in fact defective by way of shorting to ground at all times, that would also make the fan run when ever the key is turned to on.
Now in order to reconstruct this circuit correctly, you'll want to follow the path I've just laid out, in the order I've laid it out for you, that was not by accident, it was by design. When you find something that is not as I've described it, you now know how it should be, correct it then move onto the next segment.
Learn to always shoot trouble in this linear fashion. good luck amf yo-yo!
