How to Install Switch Pros in a Can-Am X3

Installing a Switch-Pros system in your Can-Am X3 is a moderate DIY project — about a 2.5 out of 5 on the difficulty scale. You don't need to be an electrician, but you should be comfortable with basic automotive wiring: identifying circuits with a multimeter, crimping terminals, and routing wires cleanly. Plan for a few hours the first time.

This guide covers the complete install: planning your circuits, mounting the Switch-Pros panel, wiring the start button replacement, installing the ground block, and setting up PTT relay control for your radio intercom.

Before you start, download and read the official Switch-Pros installation manual for your system. This guide supplements those instructions — it does not replace them.

What You'll Need

  • Switch-Pros 9100 or RCR unit (from Switch-Pros)
  • Reed Made Speed X3 Switch-Pros Mount (9100 or RCR, matched to your unit)
  • Switch-Pros Ground Block (9100 or RCR)
  • Digital multimeter
  • F-type crimper
  • Adhesive-lined heat shrink tubing
  • Basic hand tools
  • One automotive relay per PTT button (if replacing radio PTT buttons)

Step 1: Plan Your Circuits Before You Touch a Wire

This is the most important step and the one most people skip. A few minutes of planning prevents hours of troubleshooting later. Do not start wiring until you have a complete circuit plan on paper.

Why Circuit Planning Matters

The Switch-Pros 9100 and RCR have outputs with different current ratings, and assigning the wrong accessory to the wrong output will either trip the circuit under load or leave capacity on the table. Getting this right before you run a single wire saves you from having to rewire later.

Switch-Pros 9100 output ratings:

  • Outputs 1–4: 20A maximum each
  • Outputs 5–8: 35A maximum each
  • Total system capacity: 125A

Switch-Pros RCR output ratings:

  • Outputs 1–4: 35A maximum each (high in-rush — use for winch, compressor, high-draw lighting)
  • Output 9: 30A maximum
  • Outputs 5–8 and 10–16: 15A maximum each (can be combined via Set Switch Outputs for larger loads)
  • Output 17: 2A low-side driver (cannot be adjusted — use for relay coils or signal triggers only)
  • Total system capacity: 150A

How to Plan Your Circuits

  1. List every accessory you plan to control through the Switch-Pros — lights, winch, compressor, fans, audio, heated seats, PTT relays, start button, etc.
  2. Find the current draw for each accessory. Check the spec sheet or measure with a clamp meter. Use the peak/in-rush draw, not just the running draw — motors and compressors spike significantly at startup.
  3. Assign high-draw accessories to high-current outputs first. Winch, air compressor, and high-draw light bars go on the 35A outputs (9100: outputs 5–8; RCR: outputs 1–4). Don't waste a 35A output on a 3A accessory.
  4. Check your total current draw against the system capacity. Add up the maximum simultaneous draw of all accessories you might run at once. It should not exceed 125A (9100) or 150A (RCR).
  5. Plan your switch functions. Decide which outputs need momentary vs. latching, which need flash or strobe, which need memory, which need off-delay (fans, oil coolers), and which need SPDT/SP3T configuration (high/low beam, multi-speed fans). Write this down before you open the app.
  6. Plan your trigger inputs. If you want accessories to activate automatically with high beams, reverse lights, or other vehicle signals, identify those trigger wires now and plan which outputs they'll control.
  7. Name every switch before you start programming. The app allows custom names and icons — having these decided in advance makes programming faster and prevents confusion.

The RCR's “Set Switch Outputs” function allows one switch to control up to 4 outputs simultaneously — useful for running multiple light zones from one button, or combining 15A outputs to handle a larger load. Plan these assignments on paper before programming.

Use the official Switch-Pros manual for your system as your primary reference during planning and programming:

Step 2: Remove the Factory Start Button

Removing the start button is the same on all X3 models — there is a plastic nut on the back of the dash holding it in place. Remove the nut, and the button pulls out from the front.

Once the button is out, use a multimeter to identify which wire is always hot (constant battery power) and which is the switched signal wire. Do not rely on wire colors — they vary between model years. Always verify with a meter.

  • The always-hot wire will show battery voltage regardless of ignition state
  • The signal wire is what you'll connect to the Switch-Pros

In the Switch-Pros app, configure the start button circuit as a momentary switch set to Battery (not Ignition) so it operates regardless of ignition state.

Note on remote start: On older X3 models, remote starting without pressing the brake pedal requires an ECM flash to remove the brake interlock. On newer models, this may not be necessary — if your vehicle can already be started without pressing the brake, no ECM flash is needed. Evolution Powersports includes this in their tunes if you do need it. With the brake interlock removed, the vehicle can be started while in gear — use caution.

Step 3: Mount the Switch-Pros Panel

Before installing the mount in the dash, bolt the Switch-Pros keypad to the mount using the hardware supplied with your Reed Made Speed mount. Do this on the bench.

On X3 mounts, you can choose to run the Switch-Pros bezel (the snap-on plastic faceplate that adds tactile button separation for gloved use) — if so, select the bezel-compatible variant when ordering. The bezel is included with the Switch-Pros unit either way.

  1. Feed the Switch-Pros wiring through the dash hole first
  2. Insert the mount assembly into the start button hole in the dashboard
  3. Align the mount's keyway with the slot in the dash hole — this prevents the mount from rotating. Take your time here
  4. The fit will be tight — that's intentional
  5. Thread the supplied nut from behind the dash to secure the assembly

Step 4: The DESS Key

The DESS key does not need to be relocated — it can stay exactly where it is. However, for remote start to work, the DESS key must remain plugged in and present in the vehicle. This is why many builders choose to relocate and hide the DESS key plug in a discreet location rather than leaving it visible in the console.

If you relocate it, the DESS key must always be mounted in plastic — never metal or carbon fiber. If relocation leaves an open hole in the console, our DESS Block Off Plug neatly fills it.

Step 5: Install the Ground Block

Grounding your Switch-Pros accessories to the chassis at multiple points is the leading cause of intermittent electrical problems in off-road builds. A ground block gives you one central, sealed termination point for all accessory grounds — eliminating chassis ground failures permanently.

Choose a mounting location that's accessible but protected. Route the negative cable directly to the battery negative terminal — not to the chassis.

Run the wiring harness from the ground block to your accessories. Size and cut harness lengths to reach each accessory, then terminate each wire using the F-type crimp terminals from the connector kit or standard butt connectors.

A Note on Proper Wiring Technique

Every connection in your build needs to be waterproof and vibration-proof. Follow these practices without exception:

  • Use adhesive-lined heat shrink — not standard heat shrink. The adhesive melts and seals around the wire when heated, creating a true waterproof barrier. Standard heat shrink only provides mechanical protection.
  • Crimp before you shrink — make a complete, solid crimp first, then apply heat shrink. Never rely on heat shrink to hold a connection.
  • Inspect every crimp — a proper crimp deforms the terminal evenly around the wire with no gaps, no exposed copper, and no movement when tugged. If it moves, redo it.
  • Use the right crimper — a ratcheting crimper produces consistent crimps. Pliers produce connections that fail. For the F-type terminals in the ground block connector kit, use an F-type crimper specifically.
  • No bare connections — every splice, terminal, and connection point must be sealed. If water can get in, it will.

Step 6: PTT Relay Setup for Radio Intercom (Optional)

To use a Switch-Pros button for radio PTT control, you must use a relay. Never wire the Switch-Pros output directly to the radio PTT circuit — this can damage the radio and introduce a ground loop, causing engine noise on both sides of the transmission.

One relay per PTT button. Wire as follows:

  • Terminal 86 — Switch-Pros circuit output
  • Terminal 85 — ground (ground block or battery negative)
  • Terminals 30 and 87 — PTT wires from your radio (polarity doesn't matter)

Configure the Switch-Pros circuit as momentary, not latching. For a full relay wiring explanation: Del City relay wiring diagram →

Step 7: Program the App

With everything wired, open the Switch-Pros app and work through your circuit plan from Step 1. For each output, configure:

  • On/Off or Momentary — latching for most accessories, momentary for start button and PTT relays
  • Battery or Ignition — Battery for start button and anything that must work with ignition off; Ignition for everything else
  • Flash/Strobe — if needed for lighting effects
  • Memory — if you want the switch to return to its last state after the ignition cycle
  • Off Delay — for fans, oil coolers, or anything that should run briefly after ignition off
  • Overcurrent values — set each output's trip point to match your accessory's actual draw
  • SPDT/SP3T — for accessories with multiple modes (high/low beam, fan speeds) that cannot be on simultaneously
  • Switch names and icons — label every output clearly in the app
  • Set a password — anyone with the app can access an unprotected panel via Bluetooth

The official Switch-Pros manuals are your authoritative reference for programming.

Step 8: Test Before Buttoning Up

  1. Power on and verify all circuits respond in the app
  2. Test the start button — confirm the vehicle starts normally
  3. Test each accessory output under load
  4. Test PTT relay function — confirm clean audio with no engine noise
  5. Check all ground block connections for tightness
  6. Verify overcurrent trips work by briefly overloading a test circuit — the LED should flash 3 times, and the output should reset

Fix everything before the dash goes back together.
