Speedo failure/abs,brake and brake wear warning lights
 

My 1996 SL320 has the ABS, ETS, Brake wear, brake lights all on. The speedo and the economy meter are not working, otherwise the car drives OK.I have searched past posting andfound a couple of members has the same problem a while back but they have different model of cars. Member ‘ tryfunke “ has his Over Voltage protection relay replaced and fixed the problem on his 96 C220. ‘ kruger “ replaced his relay( not sure which one ) on his 1996 E 290 TD station wagon. My question is where is my over voltage protection relay located? Can somebody help?

VIN of my car is WDBFA63F8TF136046.
Thanks in advance
