Hello, I am a new owner of a 1996 Land Cruiser. I am curious what this box on the firewall is? I think it may be an aftermarket alarm system, but the car came with no alarm fob, no instructions. The car runs great but I am planning to remove this, bad idea?

Lettering or numbers on the box?
Is that a push button or lamp on the front of the box?
Any small lamp or switch on the left dash or left kick panel?
Any out-of-place small box under the driver's seat or mounted inside the cabin on the firewall by the steering column?

UPDATE:

I took the box off the firewall and confirmed that this an anti theft device. I searched online and found a phone number and talked to the guy who knows all about it. This security system used a "secret circuit" to allow the car to start. When you push the button on firewall to activate would require a second action inside the car to start. This was typically turning on the high beam headlights or a specific turn signal. At that point the system would allow current to the starter solenoid. I plan to deactivate / remove the system soon, but for anyone in the future who comes across one of these here is what he advised:

Black wire - Ground
Grey wire - Horn
Blue wire - Trigger circuit (normally headlights or turn signal but could be others
Brown wire - to starter solenoid
Green wire - ignition switch

Essentially I just need to remove everything and make sure I solder or securely (weather tight) splice the gap in the starter circuit again).

I am looking to make my 80 as reliable as possible, so this is coming out as it seems like one more thing to go wrong.

Thanks!
