After hours and hours of searching in my 1994 sl600 and through every online source, I am unable to locate the OVP relay. I bought a new OVP relay which lists application for a 94' SL600 but I am now questioning whether the car has one. One or two threads online indicate it only comes on California cars, but I note that one of the stickers on my (non-California) car shows that it meets CA emission standards. Alldata shows the OVP relay in the module compartment on the passenger side firewall area immediately adjacent to the engine's computers. However, the Alldata picture shown is entirely different than the configuration of the components in that area in my car and, most notably there is no OVP relay anywhere in the engine compartment. To know avail, I have checked all fusebox areas in the engine compartment and the trunk thoroughly.

My review of the internet threads has been equally a loss. There are several discussions about the OVP on the SL600 but, when questioned, nobody gives a straight answer where it is located. I am beginning to think the '94 SL 600 does not have an OVP relay.

If anyone knows the exact location of the OVP for the 129 series, 1994 SL600 I would sure appreciate it!!!!!

Thanks! Ray
