The harness layout for Orion has many options to make routine installations more neat. This manual is based on the most complete harness for explanation purposes. Some harness may not contain all the wires so make sure on your harness’ part number. ECU and TCU are featured here due to the overlapping of harness in use. Note that some design drawings have 2 or 3 pages. At the bottom are old harnesses that may feature in backwards installations but is no longer in production. If a harness has a V2 (Version 2) behind it then it means, there was alterations or improvements done on it. The old version will be featured below. There may be components added to reduce interference so compare your old one to the latest version to see if you need to do the modifications.
