Yeah, I have haynes service manual and it has everything there is electrical EXCEPT the horn. haha
It's OK though, I found a new way to do it. The horn is working again (I returned the air-horn because I didn't want to spend $40...hehe). What I did was cut the horn wire about 2 feet from the factory horn and sautered(spelling?) the two lines to some wire and ran that through under the dash and drilled a hole under the gauges and attached the wire to a push button I bought. Pretty nifty.
Thanks all for your help.
