Identify these wires
 

I have two photos at the following URLs:

1. http://www.granitestategraphics.com/honda/alarm01.jpg
2. http://www.granitestategraphics.com/honda/fuse01.jpg

In photo 1, from under the left kicker panel, there are four wires
going into a light gray connector. Two of the wires are green and blue.
These go into an aftermarket alarm system which was in the car when I
bought it. They appear to have been spliced into an orange wire (silver
spots) and a black/white wire (silver spots). Since this plug was
disconnected, the alarm system no longer works. Problem is, I cannot
find where to plug it in. There seems to be no empty connections in the
area under the kicker panel. Any suggestions? Also, I suspect the
orange and black/white wires are related to the A/C system. Is that
correct.

In photo 2, I noticed a disconnected, 3-pin plug one day under the
hood. Today, I found what I believe to be the match for it - in the
under-hood fuse box. I plugged it in (see yellow circle), but didn't
immediately see what might have been affected by this. Any ideas on
this one? The fuse box cover does not reference this connector.

Thanks very much in advance,
