OK, after a call to AAW I was actually able to locate the connector for the relay, can't believe I was overlooking it. It has a red and black wire and the green wire goes out to horn. So it's basically just like the other (only different) and the relay is on the cab side of the firewall. Not quite able to test it all though because I don't have my steering wheel back on yet.
