A top product from VDO but why no reasonable description? You have to get these from the Internet or browse through the small CD with unnecessary PDFs to know how to connect the instrument!
Great piece of kit. However, some issues did arise with my 1984 E21 ( Marine).
The sender unit supplied did not fit (too small). Appears BMW changed the thread size now needing an adaptor unit for the new unit to fit! Thought this might have been included to cover the changes made. Wiring instructions for the guage were very limited needing much online searching. A simple diagrammatic drawing would greatly assist Apart from the above the product looks exceptionally good yigetger with the service.
