Looks like any of a million cheap / crap alarm/immobilisers. They all use black wires so it's not obvious which wire goes where. Usually installed by butchers who cut and shut the wiring harness with anything from scotchloks to solder wrapped in cheap PVC tape.
Your best bet is to open it up and see if there are any manufacturer logos/tell-tales on the PCB, google and contact them (if they're still in business). Otherwise, follow every wire, cross check it against the vehicles wiring diagram and try and undo the damage.
Usually wires to the indicators, horn and in series with either the ignition or starter motor.
