If you are lucky you may find the wiring colours at each plug are the same and only the plug shape is different. Some of the wire colours changed over years and some wiring diagrams don't agree with one another (eg the Haynes and Bently manuals dont agree on colours, I even have two Haynes manuals that cover the same models, that are published in different years and they don't agree either) All the manuals do however agree on the pin numbers Quote Share this post Link to post Share on other sites
