History
•This new style Level 2 harness was developed for Orion2 to save install time and
minimize fault-finding afterwards. The harness contains all TxW connections from all of the Connectors and will serve most TxW combinations.
•This harness is designed to use as a Standalone option where there is no ECU present like Carburetor or Diesel engines. It has the RPM and TPS sensor in shielded sleeve to connect directly to the sensor on the engine. It has power and earth wires included in the shield. In some cases you may need to build a sensor onto the engine.
•It is the recommended Wire and Play loom that has the relay and fuse pre-wired in the loom. No need for extra power wires etc. It is designed to contain all the TxW connection wires so that all connection options on any throttle and pedal are possible. The manual is also based on this harness structure for wire colours and placement.
•Diodes and resistors for decoupling and pull-ups are already built into this harness.
Design Points to take Notice of.
•It comes with PVC sleeving and heat shrink to dress up upon final installation. You will still need the connectors of the throttle and pedal as this is an universal harness. It is not Plug and Play.
•This harness comes with a Mechanical relay that are wired according to TxW
requirements. The Relay has a Inline Fuse for protection.
•All the input wires are shielded and is earthed on the TxW side with the small black lead that must be connected to the TxW earth. Never connect a shield on the Engine or chassis of the car.
