Overview

Products that can use this harness
•Orion2

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 with ECU systems. It has the RPM and TPS wires unshielded to connect directly to the ECU signals. On Spitronics ECU’s there is already wires included in the loom with the same colours where it must be connected. On OEM ECU’s you may need to splice into their signal wires.
•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.
