VDO speedometer wiring
Ok, First I want to say that I have read all the old threads, posts, and the techarticle about this subject, and I apologize if it has been beat to death, but one key element has been left out here. I have a new electronic sender #YBE 100540. I asked for the #AMR 1253 but the dealer said is superceedes to this number and it is that same part. There are two terminals inside the plug. Which one do I use for the signal, and what do I do with the other one? Ground it? Power it? Ignore it? I have the rest of the install covered, but this is a sticking point for me. Thanks in advance for your help.
