Disconnect Battery
Before touching anything electrical:
- Turn the bike on
- Disconnect the battery
- Wait a few seconds for the system to discharge
This prevents shorts, controller damage, and accidental sparks.
Tools You’ll Need
Mechanical crimps are preferred over solder for reliability and vibration resistance.
- Brass crimp terminals
- Self‑adjusting wire stripper
- Wire crimping tool
- Dual‑temperature heat gun
- Electrical loom tape
- 30mm heat‑shrink tubing
Domino Throttle and Switches
Use these known‑compatible parts to match the wiring tables below:
If your switch uses different colors, request a wiring diagram before proceeding.
Good Lighting
Work in a bright area. Misreading wire colors can permanently damage the controller.
Mode Switch Wire Warning
The yellow and green wires are both positive on the ONYX RCR.
- Never allow them to touch while powered on
- Doing so will damage the controller instantly
Avoid Soldering
For vehicle wiring:
- Crimping is stronger under vibration
- Handles heat cycles better
- Maintains lower resistance
- Avoids brittle joints
Only solder:
- Battery charge connectors
- Battery discharge connectors
Everything else should be crimped.
Domino Throttle Install Instructions
This install reuses the stock throttle harness. No new wiring runs are required.
Preparation
- Cut the Domino throttle connector off (leave 1 inch)
- Locate the stock throttle cable
- Cut it 2 inches from the throttle housing
Harness Prep
- Slide 5 inches of heat‑shrink onto the bike harness
- Strip 2 inches of outer insulation from all bundles
- Strip ½ inch from each individual wire
Wiring
- Match colors using the tables below
- Crimp each joint
- Wrap each joint with 1½ inches of loom tape
Testing
- Reconnect battery
- Power on
- Test throttle
- Test power switch
- Test mode switch
If all works:
- Power off
- Slide heat‑shrink over joints
- Shrink evenly using heat gun
- Stop once fully sealed

Final Notes
- Double‑check wire colors before crimping
- Never test wiring with exposed connectors
- Do not hot‑plug switches
- Keep harness strain‑free
A clean throttle install improves response, reliability, and long‑term controller health.
