Product Overview
The Spitronics X05 TxW Harness is a universal Level 2 wiring loom developed for the Mercury3 ECU system. Designed to simplify electronic throttle installation, this harness brings together the required throttle-by-wire connections in one organised loom, helping reduce installation time and minimise potential fault-finding during setup.
The X05 harness includes the connection wiring required to accommodate a wide range of electronic throttle body and accelerator pedal combinations. Its pre-wired relay and inline fuse, together with integrated diodes and resistors, provide a practical wiring solution for supported throttle-by-wire configurations.
Key Features
- Universal TxW Compatibility: Includes connection wiring to accommodate most electronic throttle body and accelerator pedal combinations.
- Pre-Wired Relay and Fuse: Features a mechanical relay wired for throttle-by-wire requirements, with an inline fuse for protection.
- Integrated Electronic Components: Diodes and resistors are built into the harness for decoupling and pull-up requirements.
- ECU Signal Connections: Includes dedicated RPM and TPS signal wires for direct connection to the ECU signals.
- Shielded Wiring: Shielded pedal TPS and throttle wiring helps support the signal connections required by the system.
- Installation Finishing: Supplied with PVC sleeving and heat shrink for dressing and finishing the loom during installation.
Wiring Connections
The X05 harness includes wiring for the following connections:
- Pedal TPS: Shielded TPS signal (blue), +5V supply (red), and earth (black).
- Electronic Throttle: Shielded throttle motor positive (red) and negative (black).
- Ignition Power: Orange wire.
- TPS Input Signal: Yellow wire.
- RPM Input Signal: Green wire.
- Water Temperature Sensor: Blue wire.
- Battery Positive (BAT+): Red wire.
- Screen and Sensor Earth: Black wire.
- Relay Wiring: One set of four relay wires.
Refer to the X05 harness design drawing for the specified wire thicknesses and lengths.
