Hi, I have a Mercedes 190e W201 1987. I have a relay in place for R1 and R2, but none for R3 and R4. But no R3 and R4. R3 – Auxiliary Fan Relay – not sure where this is in the car? R4 is for OVP – I have an OVP elsewhere in the car behind the battery. Do I also need a relay in the fuse box? If so do you know where I can get it? Thanks. Perera PS you have a useful site for these older 190e’s.
THIS IS REALLY VERY USEFUL. GREETING FROM SOUTHERN MOROCCO.
