I'm afraid I left out one important wire path in the wiring description I sent along in the comments added to Colyn's last post....

Use the #1 common and NO terminals on the A/P relay to send the "engage" signal to the A/P.  You'll obviously need to verify just what your particualr A/P is looking for there, whether it's a ground or a positive signal, and send whichever is appropriate to your A/P through those relay contacts.  Sorry I left them out of the earlier post.
