After test drive dash gages quit, coolant temp still registers, all other guages quit working, Speedometer, Tach, fuel gage, voltmeter all failed at the same time. This is a Japanese SL600 sport coupe. We have not been able to locate the OVP relay? Pulled the cluster, W1 ground looks good for all wires connected there, have power at 2 points coming into the cluster round plugs KOER. Fuse 1 and 5 are good for power in the main block. Does anyone have pictures of the round cluster plugs with location coding, I have the wiring diagram for the cluster but it isn't helpful in this regard. Gages were working fine up to this moment. Will appreciate any incite into this car and why this problem might have suddenly occured. Tx Mark
