Attach the main lead directly to the input terminal of the assembly. Ensure the ignition is off and the battery disconnected to prevent short circuits or sparks during installation.
Identify each wire by color and function before connecting to the module. Red typically carries the positive signal, black the ground, and any additional wires control relay or sensor inputs.
Secure each connection with proper terminals and ensure no exposed strands remain. Loose contacts can cause intermittent operation or complete failure of the delivery system.
Route the lines along existing channels and fasten with clips or ties to prevent vibration damage. Avoid sharp bends and proximity to high-heat components to maintain long-term reliability.
After completing the connections, test continuity and resistance using a multimeter. Confirm all leads match their intended terminals before restoring power to the vehicle.
Check the operation of the delivery module under ignition cycles and ensure smooth activation. Any irregularities suggest misconnected or damaged lines that require immediate correction.

Attach the main lead directly to the positive terminal of the assembly. Ensure the battery is disconnected before handling connections to prevent sparks or short circuits.
Identify each wire according to its color code and function. Red typically carries the positive signal, black serves as ground, and additional lines control relays or sensor signals. Labeling each conductor prevents misconnection and ensures proper operation.
Secure all terminals tightly and route the lines along existing channels using clips or ties. Avoid sharp bends or contact with hot components to maintain reliable performance, and test continuity with a multimeter before restoring the vehicle’s power.
Identifying Connector Pins and Wire Functions
Locate the main assembly and inspect each terminal. Red leads carry the positive supply, black leads serve as ground, and any additional wires handle relay activation or sensor input. Use a multimeter to verify continuity before connecting to the module.
- Mark each wire at both ends to prevent misconnection.
- Check insulation integrity to avoid shorts or interference.
- Confirm pin orientation matches the assembly’s specifications.
- Test for proper voltage levels before restoring the vehicle’s main power.
