Nope but others here can.

One thing I can say though is that the 2 fuse relay should only be used on the 90 and later cars. Your 89 should only have the 1 fuse relay.

This runs counter to all the advice I've ever read and heard on the subject. In fact, my 1988 was specifically "upgraded" to the 9-pin, 2-fuse version by my long-time MBz mechanic many years ago.

Ned, a few years ago my parents' 1995 E320 started running poorly and the OVP relay buzzed ... probably due to weak solder connections. Replacing the OVP relay resolved the problem.

What are others opinions on this? Meaning no slight here but I'd be interested to hear more opinions.

On this thread: M-103: too many issues for the title... at post number 10, GSXR, who we all know is one of the sharpest guys around, said this: "Early OVP's have one fuse, later OVP's are a different design and have two fuses. They are NOT interchangeable."

Hmmmm..... Not Interchangeable. Where did he get this info? Considering that a dealership specifically sold me a two fuse version specifically mentioning that M.B. had updated the OVP and FPR over the series of cars that they were used in and that the latest version of each is the proper unit to use.
My car works perfectly fine with either version - one or two fuse.
