As one of the premiere manufacturers of motorcycle-specific security systems, Scorpio holds a reputation for its motorcycle alarm systems. Despite the apparent complexity of the Scorpio alarm's two-way communication system, which alerts the motorcycle's owner of a disturbance, the system is easily installed on almost any motorcycle that is equipped with a battery. Although Scorpio offers model-specific wiring harnesses to simplify installation, using the included universal supplies to install the alarm is nearly a plug-and-play experience.

Instructions

  1. 1

    Lay out the contents of the alarm's installation kit and components. Ensure that the wiring harness and all the T-tap connectors are present.

  2. 2

    Access your motorcycle's electrical system and battery. For most motorcycles, the electrical system is hidden beneath the rider's seat. Remove the seat, either by unlatching or unbolting it, and set the seat aside. Disconnect the battery's negative (-) terminal using a Phillips screwdriver to unscrew the terminal bolt. Move the negative (-) terminal away from the battery, keeping it clear of the motorcycle's frame to prevent a short circuit.

  3. 3

    Mount the alarm's control module under the rider's seat or frame side cover. Clean the mounting location with an alcohol wipe to remove any dirt or oil. Place a strip of Velcro onto the mounting location and maintain pressure on the strip for 30 seconds. Apply the matching Velcro strip to the back of the control module, applying pressure to the strip for thirty seconds. Mount the control module onto the motorcycle.

  4. 4

    Route the control module's antenna lead along the motorcycle's frame, avoiding moving components to avoid damaging the antenna. Secure the antenna with zip-ties as needed.

  5. 5

    Connect the main wiring harness to the control module. Route the black wire lead with the ring terminal to the battery' positive (+) terminal. Unscrew the battery's terminal bolt using a Phillips screwdriver and install the control module's ring terminal onto the battery's positive (+) terminal. Insert and tighten the terminal bolt with a Phillips screwdriver.

  6. 6

    Connect the secondary wiring harness to the main harness's four-pin connector. Use T-tap connectors to splice the secondary wiring harnesses leads into the motorcycle's electrical system. Connect the black lead to a known ground wire, such as a tail light ground wire. Connect the pair of grey leads to the turn signal power wires. Connect the orange lead to a power wire that is connected to the ignition switch, such as a tail light or headlamp. Secure all loose wires to the motorcycle's frame with zip-ties.

  7. 7

    Reconnect the battery's negative (-) terminal, tightening the terminal bolt with a Phillips screwdriver. Replace the frame side cover or rider's seat.

Tips and warnings

  • Have the work performed by a qualified motorcycle technician if you are not comfortable working with your motorcycle's electrical system.
  • Plan ahead to save time. Inspect your motorcycle for suitable mounting locations before installing the alarm.
  • Do not allow the battery's negative (-) terminal to contact the motorcycle's frame. A serious electrical shock or short circuit could occur.
  • Avoid placing the alarm's wiring near moving components to reduce the risk of damage.
