Switch Pros Can-Am X3 Start Button Replacement

Replacing the start switch with the Switch-Pros is straightforward. With the OEM start button removed, you can use an electrical multimeter to test which plug terminal is always on. On the 2020 model, the Beige with White striped wire should always be hot with the same voltage as the battery. This wire belongs to fuse position 8 in the fuse panel behind the driver’s side seat on the rear firewall. It should be a 10-amp fuse. In the 2020 model, the other wire is Black with a Yellow stripe. Different model years may have different color wires. This is the wire we will want to connect to the Switch-Pros. In the Switch-Pros app on your phone, it does not matter which button or circuit you use, as long as you set it up as a momentary switch with constant battery power, not ignition. If you use Bluetooth to remote start the car, you will need to have a tuner remove the brake function in the ECM at startup. Evolution Powersports offers this on all of their tunes, and I believe they call it race start. This will remove the need to have your foot on the brake to start the vehicle. But you must use caution, as you can now start your car while it's in gear.

Which wire is the signal wire on the Can-Am X3 start button? 

On the 2020 model, the Black with Yellow stripe wire is the signal wire. The Beige with White stripe is always hot. Wire colors vary by model year — always verify with a multimeter before connecting anything. 

How do I configure the start button in the Switch-Pros app?

Set the circuit as a momentary switch with constant battery power, not ignition. This allows the start button to function regardless of ignition state, including for remote start.

Do I need an ECM tune for the remote start to work? 

On older X3 models, yes — you need a tuner to remove the brake interlock in the ECM. Evolution Powersports includes this in their tunes. On newer models, it may not be required. With the interlock removed, the vehicle can be started in gear — use caution. 

Does the DESS key need to be relocated when installing the Switch-Pros mount?

No. The DESS key doesn't need to be relocated. However, it must always be mounted in plastic — never metal or carbon fiber. We often hide it so the key can stay in and we can remote start the car. A billet DESS block-off plug cleanly fills the original port.
