old code alarm pro 5000

Hi - newly registered user here with an introductory question...

I recently purchased a 1990 Ford Mustang LX Convertible which has a once seemingly well installed Code-Alarm Pro 5000 unit.  The PO has since dislodged the main unit and the underdash switch panel.  I need info about this unit such as what its capabilities are?, how to use the 4 button remote (top left is arm/disarm with lock/unlock, top right is trunk - other two unknown) ?, what the two switches and single push-botton under the dash do ?, what the LED sequences mean ?, etc - basically I need an owners and installers manual.

The alarm seems to work fine, but I need to know how the whole thing works.  I have done searches online for hours and come up with nothing.  I can't even seem to find a reference to this model anywhere.  There is a wiring schematic sticker on the back of the unit with a date of 8/92.  Anybody have something to offer on this one?

Thanks,

Herb

Hmm... acutally it looks like only the installation manual is there.  (And keep in mind it's listed as "PRO 3000 THRU 7000 INSTALL"). 

There is also a document section here, although I assume you've already looked.

The button is for programming/overriding the alarm if you need to activate a special feature or turn the alarm off if the remote is broken or lost.  The switch is labeled as a "valet switch," which I'm assuming if on it prevents passive arming from occuring.  I'm not sure what the second switch would do unless it is for an accessory or something else.

If it seems like the other buttons aren't doing anything, they may be to trigger an optional accessory circuit for which there is nothing connected to. What do they say?

Sorry I can't say too much about it... In August of '92, I was beginning the 1st grade...
