I found the OVP relay area above the fuse box, but there were 5 different fuses. There was a set of three, and above it, a set of 2. Can anyone tell me which of these 5 is the OVP relay. My 85 380sl is running rough and the antilock brake light is on and I think this is the culprit. If not, I will have vacuum checked next. Thank you. This is a great sight....lots of info here.
