I have the opportunity to buy a used V-AFC for a VERY good price. My concern is how easy it will be to install.

Having never installed one before, I don't know what's involved. For such a low price, I assume I'm going to get the V-AFC itself and the wiring harness ONLY. None of the extra stuff. What else is supposed to be in the box? How easy is it going to be to replace? It was installed on a 94 EX before, and I want to use it on my 97 EX .. is that going to be a problem?

It's a good price, but not worth it if I have to buy 50 bucks worth of stuff to make it work, and spend hours hacking stuff apart. Can anyone who has installed one of these let me know what I should check for before I buy?
