Keyless Entry - cannot find

I'm not familiar with that model alarm, but you might be able to download an installation manual at their website; this will list the functions of each of its wires. In general, though, look for a two-pin or three-pin plug that sits all by itself. The middle pin is likely to be constant positive, and the two outer pins would be your lock and unlock outputs. Test the two outer pins while operating the alarm remote, and see what you get.

The Ungo SAS6400 alarm system is more than 10 years old alarm system. It has on board relays for the keyless entry system. Here is the diagram: http://www.techneltd.com/6400-di.htm http://www.techneltd.com/doorlock64-65.htm
