The colour codes above may not be the exactly same as on your car or engine (some of mine were different) depending on the year but they will usually be pretty close. 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

how much did it cost you to get the parts from Germany. What was the freight like and how long did it take to get here.
