How to remove a 95 honda accord lx alarm system?

Hi, i'm currently buying an automatic 95 honda accord lx and the alarm seems to be draining the battery, i'm interested in just disconnecting the alarm, not arming a new one in hopes that it no longer drains the battery. As for the alarm, i have a feeling its an after market one considering there's no honda symbol on it and only has an a, and a, d on it. I removed the sub dash in hopes of seeing the device in an obvious spot i didn't really have the time to look deep under the dash or anything so i didn't see any obvious box, as far as having an ignition kill switch there's a button undering the steering wheel slightly under the dash i'm guessing thats what it is, not exactly sure. I've watched a good bit of videos on it, couldnt find this exact model. So bottom line i just want to know if i'm doing the correct thing or if i should look under the hood? I still have to pick the car up and bring it home, i also don't have enough info on the alarm system too, so how can i identify it if its under the hood?
