What are the advantages and disadvantages of doing the cooling fan override mod?
None, except if you race on a track, mine is not done yet, but when you wait to have a run you can flip the switch and the engine will stay a bit cooler if you can't stop the car. It's the only reason to do that, at least I think.
As stated for racing, you can run the fan while the car is off and sitting to help cool it faster. Also if you have been driving the car and you are going to work on it, you can use the fan to help cool it off.
Down fall is the fan takes a lot of juice to run, and can take it's toll on the battery. Trust been there. Still worth it.

Also its a pain the boot to wire it in the really small really box. And dont try in cold weather unless you have a heated garage. It will be to hard to not hurt yourself in the process.

racing isnt the only advantage...i use it quite often in texas traffic..sitting still at quiting time then get a brake away i like to keep the engine cool so i dont have over heating problems...and maybe ive been reading the wrong diagram but it seems the way i wired mine was MUCH easier than the instructions...i simply cut into the green wire..ran it to the switch..then to ground...anyone else done this??

So all you do is giving ground to the relay?? I'm making it different, the only wire that will join the factory ones, will be the wire that goes to the fan itself. Mine is simple, a wire starting from the battery splicing in two to give positive to the relay, one of the wire get in the car to the switch (in the small compartment for money and stuff, behind the shifter), the other one simply go to the existing wire to fan. I'll just see if I got a CEL that way, cause when you plug it on the existing relay, you may get one, cause the pcm will see that it's not him who gave the ground to the relay....
Forgot to say that if you do it like I do, you need a fuse, because you don't want to melt the wires if something go wrong
