Answer
Had no luck in getting pin out info for the equipment you want to wire in your aircraft. However there is a book available that claims to supply this information for all the aircraft electronics. May even be of help for you to wire the package. If you purchase it and have any problems I can then help you make the proper wiring decisions. Here is the web site. http://www.actechbooks.com/products/act056/

Appears to be a good book for someone active in the business that does not have all the dealerships to obtain the technical data. Always willing to help.
