    What are the 3 relays?

    What are the three relays on the harness that mount to the body. I believe one is a fuel pump the other is a main/dme but what is the third relay? Engine is from a 1995 325is. If anyone has the relay part number that would be cool too!!!

      Fuel Pump, O2 Heater, Control Unit.
      The first two are normally orange and are the same part number.
      The last is normally white.
      Sorry, I don't have part numbers on hand...

          I have seen the orange relays before but mine are white (2) and mint green (1) I believe you are correct on the third being the o2.

              That's definitely what they are for, just try to find the part numbers. They should be printed on the top of the relays.

                  What exactly does the O2 heater relay do?

                      It turns on the O2 heater once the engine reaches a certain temp. It's necessary for the O2 sensor to take proper readings.
