The 3 wires could be your optional Aux connection, should have a plug. Doesn't go anywhere, unless of course you have an aux input.

When the Almanac is gone that means you lost power somewhere and lost the memory. Since, you don't have sat coverage, your car will not be able to get the Almanac (Date and time). It will have to do a search and this could take a little while...I do not know the time frame for this system.

Just make sure everything is tight, fire her up, and see if the system reboots. I would wait at least 15 minutes to see if it acquire sat coverage.
