Looking for the OVP relay location on the W140, reading through the forums, I find out from Sixto that W140 bodies do not have a OVP they have a base module located on the pasenger side front of winshield, plastic cover four hex screws, 3 fuses 10 amps each. replace the bad one and car came to live again. I'm so happy for this site. If anyone need a pic please let me know.
