How to go about testing the upper wire harness on a 1994 S420? any hints
The question is how to test for broken wires

Check for the white tag with Delphi printed on it. The tag is up by the harness connector.

I have yet seen an updated harness have a broken wire. Once the harness is replaced, it is done.
