WARNING:  If you are not comfortable or familiar with working with your vehicle, we STRONGLY recommend having your Kill Switch professionally installed by your local mechanic or stereo installation shop.

Installation of the Wireless/Remote version [watch installation video]

IMPORTANT NOTE: The Wireless Unit does consume power (0.03amps) when set to ‘disable‘ (OFF button on remote) vehicle but more (0.30amps) when set to ‘enable‘ start (ON button).  Make sure you set to ‘disable’ if you park your vehicle for a prolong time to mitigate battery power usage. 

Wireless Remote — Common Questions

The remote has a working range of approximately 150 feet in open line of sight. Anything between you and the vehicle reduces that range — buildings, walls, parking structures, other vehicles, and nearby radio interference. Inside a parking garage or through a building, expect noticeably less than 150 feet.

The remote lights up: a light on it comes on when you press a button. That light shows the button was pressed — it does not show whether the Kill Switch is armed or disarmed, and the vehicle does not chirp or otherwise confirm the change.

Press ON to allow the vehicle to start. Press OFF to arm the Kill Switch, which prevents the vehicle from starting. Hold the button for about a second.

If you are not certain a press went through, press the same button again. Extra presses do no harm — the system simply stays in that state.

IMPORTANT NOTE:

The Bypass Relay in your Kit will ONLY have 3 Pins total (vs. 4 or 5 on your OEM relay). This is intentional in order to bypass the signal.

IMPORTANT NOTE FOR TYPE 1 – LARGE BODY KITS:

Type 1 – Large Body kits are used mainly on 1999-2007 Chevrolet, GMC and Cadillac trucks and SUVs. If you have one of these, please read this before you start.

If your vehicle has an aftermarket remote start or alarm fitted, please contact us before installing. Once the kit is installed, complete the extra safety check at the end of these instructions, right after the TEST THE KILL SWITCH step.

OVERVIEW Installation Instructions:

  1. Replace factory Starter Relay with Bypass Relay Module (other end to Control Module)
  2. Connect Ground Connector to Neg Batt terminal or Chassis ground (other end to Control Module)
  3. Run Harness for Toggle Switch to cabin and connect Toggle Switch (Hide Toggle Switch in location only you know) (other end to Control Module).
  4. Done!
**IMPORTANT NOTE** The Kill Switch disables the Starter but does not disable the fuel pump. On some older vehicles or vehicles with a standard key, excessive cranking (attempts to start your engine) with the Kill Switch engaged may pump excess fuel and temporarily flood your engine.  
 

Detailed Installation Instructions

Step 1:

Replace your vehicle’s Starter Relay with the Relay Bypass Module.

      1. Your vehicle’s starter relay is usually located in your primary fuse box under the hood. If you flip over your fuse box cover, there should be a diagram identifying which relay belongs to your vehicle’s starter. (Pro Tip: Depending on your vehicle, the RELAY identifier can sometimes be abbreviated “ST” or “STR”, “START“, etc.  Do not mistake similar positions such as “run/crank” or “start/stop” which make have similar initial no-start effects but will cause strange running side-effects.
      2. IMPORTANT: To make sure you pulled the correct relay, try starting your vehicle with it removed. If the engine starts and runs, you pulled the wrong one. With the correct starter relay removed, you should hear a click but no sound of the starter cranking. If your vehicle uses the fuel pump relay instead, the engine may still crank, but it should not start and run. It is VITALLY important you replace the correct relay–some vehicles have several of the same relays and the orientation of the diagrams can be confusing. Please take your time and double-check the correct relay. 
      3. Once you are sure you pulled the correct starter relay module; replace it with the 41.22 Relay Bypass Module. **NOTE** Type 1 modules, if turning off the Kill Switch fails to start your engine, the orientation of the bypass relay is incorrect; just flip it the opposite direction and it should function thereafter. 

IMPORTANT: If your Kit has an extra Bypass Relay labeled “Reverse Relay”, this is in case the pre-installed relay does not work. In that case, your vehicle may have a reversed negative pin, so just swap out and use the packaged “Reverse Relay” instead. If you did not receive a reverse relay and the one that came in the kit does not work, please contact us. We’re happy to ship you a Reverse Relay if you need it in your case.

Step 2:

Mount the Control Box

  1. Mount the Control Box near your fuse box; making certain you do not over-stretch the wire connected to the Relay Bypass Module.  Choose a location that neither the Control Box or wires rubs against any pipes or hot engine components.
  2. You may attach the Control Box via the screw mount tab or use double-stick tape.
    1.  
 

Step 3:

Connect the ground to the negative terminal of your vehicle’s battery or a good chassis ground (you must ensure a good ground).

Step 4:

  1. Run the Switch harness from your engine compartment into your cabin.  Most vehicles will have a firewall pass-through grommet hole (example below on a Jeep JT).  Make certain the harness does not come in contact with any hot engine components or hangs loose.
  2. Attach the harness to the included Toggle Switch with the crimp butt connectors (RED wire to RED, BLACK wire to BLACK wire).  You may also use any aftermarket toggle switch of your choosing–be sure it is a SPST type.  
  3. In your cabin, you will want to hide your Switch somewhere you can reach while in the driver’s seat but not obvious to a potential thief.

The Toggle Switch can be hidden just about anywhere; in the example below, it’s hidden behind a radio–with just enough of the Switch tip showing for easy toggling.

TEST THE KILL SWITCH by toggling it off and trying to start your vehicle–it should only click and not start.
Now depress your vehicle’s Start/Stop button into the OFF position, toggle the Kill Switch to the ON position and start your vehicle.

EXTRA SAFETY CHECK (TYPE 1 – LARGE BODY KITS): With the Kill Switch ON, the starter should only turn while you are turning the key. If the starter ever engages or keeps running on its own, turn the Kill Switch OFF immediately, and if that does not stop it, disconnect the battery. Please do not use the vehicle again until you have contacted us – we will sort it out.

WE STRONGLY SUGGEST keeping your factory relay in a safe place hidden in your vehicle so in the event your install wire(s) come loose or you need to restore it back to factory you are able to quickly.

CONGRATULATIONS!  You are now protected!
