Introduction

Installation instructions for the IOX-KEYLESS solution with SID (Starter Inhibit Device) using the HRN-SIFUSETAP harness.

    • WARNING! Installation of this product into vehicle systems requires professional installation by a qualified technician who is thoroughly familiar with any circuits involved.

    • Installing the Geotab SID solution requires real-time access to the host vehicle wire interface diagrams for starter control (i.e. ALLDATA™, WireSheet™, Mitchell1 ProDemand™ / eAutoRepair™ or equivalent). Typically, the diagrams are provided to car security solution installers.

    • WARNING! The Geotab SID solution must not be installed in such a manner where it has the potential to disable propulsion and/or prevent vehicle control while the vehicle is in motion.

    • Never install a circuit interrupt on any circuit that may interfere with the safe operation of a vehicle or cause the engine to stop while the vehicle is in motion — such as fuel lines, brake switch, or multiplexed circuits.

    • Some vehicles stop the engine every time the vehicle comes to a stop, and automatically restarts the engine upon pressing the accelerator pedal.

    • Installers in these vehicles need to ensure activation of the Starter Inhibit feature does not disable the vehicle in a precarious location (i.e. a busy intersection) and does not leave the vehicle unable to move to a safe location or other direct or indirect effects resulting from the installation of the Starter Inhibit feature.

  1. This installation guide covers the installation of the HRN-SIFUSETAP - Starter Inhibit Harness for IOX-KEYLESS. The following fuse interrupters are available to use with the HRN-SIFUSETAP harness to interrupt a circuit in the vehicles fuse panel:

    • Locate and access the vehicles fuse panel.

    • Some vehicles may require you to remove dash panels / covers to access the fuse panel.

  3. Locate and test the fuse for Starter Interrupt using a Digital Multimeter. Ensure the fuse does not interfere with safe operation of the vehicle and does not cause an permanent fault codes to be displayed on the vehicle dashboard.
    • Locate and test the fuse for Starter Interrupt using a Digital Multimeter.

    • Ensure the fuse does not interfere with safe operation of the vehicle and does not cause an permanent fault codes to be displayed on the vehicle dashboard.

    • The fuse used for Starter Interrupt should prevent the vehicle from starting when the engine is off.

    • The engine should remain running if the fuse is disconnected from the vehicle while the engine is running.

    • It is highly recommended to refer to vehicle wire interface diagrams for starter control (i.e. ALLDATA™, WireSheet™, Mitchell1 ProDemand™ / eAutoRepair™ or equivalent) to locate the starter wire in the vehicle.

    • Remove the fuse and verify the HOT side of the fuse slot with a digital multimeter.

    • When testing the HOT side of fuse slot, also check to see if the fuse is a Constant 12V/24V or a Switched Ignition circuit.

  4. Insert the Fuse Interrupter into the fuse slot. The HRN-INTX21ATC - ATC Fuse Interrupter is used in this example. Ensure to use the correct Fuse Interrupter for your application.
    • Insert the Fuse Interrupter into the fuse slot.

    • The HRN-INTX21ATC - ATC Fuse Interrupter is used in this example.

    • Ensure to use the correct Fuse Interrupter for your application.

    • Ensure the Black Wire on the Fuse Interrupter is connected to the HOT side of the fuse slot.

    • Connect the White 2-pin Molex connector from the Fuse Interrupter to the White 2-pin Molex connector on the HRN-SIFUSETAP harness.

    • Using the supplied fuses, insert a fuse of the same rating as the one that was removed from the vehicle into the Black Fuse holder on the HRN-SIFUSETAP harness.

    • Ensure the connection is secure.

  5. The supplied flying lead harness in the HRN-SIFUSETAP harness kit may be used instead of the Fuse Interrupters to interrupt the starter circuit. Using a digital multimeter, locate the START (cranking) wire — the wire that is at 12V / 24V when the key is in the start position. It is highly recommended to refer to vehicle wire interface diagrams for starter control (i.e. ALLDATA™, WireSheet™, Mitchell1 ProDemand™ / eAutoRepair™ or equivalent) to locate the starter wire in the vehicle.

    • It is highly recommended to refer to vehicle wire interface diagrams for starter control (i.e. ALLDATA™, WireSheet™, Mitchell1 ProDemand™ / eAutoRepair™ or equivalent) to locate the starter wire in the vehicle.

    • Cut the starter wire.

    • Connect the Black wire (HOT SIDE) to the +12V/24V signal and the White wire (COLD SIDE) to the starter.

    • For all connections, strip 1/2" (15 mm) of insulation, solder, and insulate the connection using heat shrink or electrical tape. Ensure the connections are secure.

    • Connect the White 2-pin Molex connector from the Fuse Interrupter to the White 2-pin Molex connector on the HRN-SIFUSETAP harness.

    • Using the supplied fuses, insert a fuse of the same rating as the starter circuit of the vehicle into the Black Fuse holder on the HRN-SIFUSETAP harness.

  6. If the HOT side of the Fuse Interrupter is on a switched ignition source, proceed to connect the Black molex connector (Yellow wire) from the HRN-SIFUSETAP harness to the Black molex connector from the Fuse Interrupter connection point (2-pin white molex connector).
    • If the HOT side of the Fuse Interrupter is on a switched ignition source, proceed to connect the Black molex connector (Yellow wire) from the HRN-SIFUSETAP harness to the Black molex connector from the Fuse Interrupter connection point (2-pin white molex connector).

    • If the HOT side of the Fuse Interrupter is on a constant +12V/24V source then proceed to the next step.

    • Ensure the connection is secure.

  7. Use the Yellow Ignition pigtail provided with the HRN-SIFUSETAP harness kit to find a true Ignition source +12V / +24V. This ignition source is used to energize the relay.
    • Use the Yellow Ignition pigtail provided with the HRN-SIFUSETAP harness kit to find a true Ignition source +12V / +24V.

    • This ignition source is used to energize the relay.

    • The Ignition source should have +12V / +24V when the Ignition switch is in the ON/RUN and Start positions and should have 0V when the Ignition switch is in ACC or OFF positions.

    • IMPORTANT: Do not connect the yellow wire to a constant power source nor to the vehicle's battery. This can result in the relay constantly draining the vehicle's battery.

    • A Fuse adapter may be used to connect to a location in the fuse panel for the ignition source.

    • The fuse adapter must be supplied by the installer / technician.

    • Use a Digital Multimeter to verify before making the connection.

    • Ensure the connection is secure.

  8. Locate a suitable chassis-ground point. Connect the ring terminal from the HRN-SIFUSETAP harness to the chassis ground.
    • Locate a suitable chassis-ground point.

    • Connect the ring terminal from the HRN-SIFUSETAP harness to the chassis ground.

    • A self-tapping screw can be used to secure the ring terminal to a part of the metal dash frame.

    • IMPORTANT: Ensure there is no wiring or objects behind the location of the ring terminal prior to drilling.

    • Ensure the connection is secure.

  9. Plug the supplied relay into the 5-pin relay socket.
