Brian, this question comes up so much, and so much is written on the subject that a search would yield more information than you would get in one post, plus save myself personally from typing not just the answer to your question, but everything else you need to know (but don't yet know enough to ask) to get your problem smoothly fixed.

For example, if you search using keywords "engine wiring harness" and my username, you'll get information that it is available from Fastlane... you'll find the recent prices for the wiring harness... the fact that there are two different styles for the 95 E320.... and where to find the part number so Phil can order the correct wiring harness and save you the grief of having to deal with a return as I had to deal with.

Please do a search, then come back for any other questions and clarifications that you want us to address.
