Subaru 4 Pin Brake Switch

Recommended Posts



I am in the progress of fitting cruise control to my 2010 Subaru legacy


I’m after a 4 pin brake light switch that I seem to find easily everywhere online. But unfortunately I am having a very hard time finding the 4 pin connector that plugs into it.


Is there any chance anyone would be able to tell me what the part number would be or where to find it? I had a chat to someone from PartSouq and they were unable to help me without a part no.. 


Also, would anyone be able to give me info as that which ECU pins I need for wiring the 2 required wires to it? 


This is what I need:


1.    Brake light switch (PN: 83370AA001) easy to find – or the alternative:




2.    4 pin male connector to go into the above (no idea where to find) –





Any help would be greatly appreciated!

following - how would one know if your Sub is compatible to upgrade to CC?

Hi HannesNel,


I have been following this thread: Brilliant write up by  @richnorm


I'm not sure if there is an exact way to tell if it is compatible but I have a mate with the exact same model as mine (but has CC) and apparently most newer cars already have it programmed into the ECU


I have added in the steering wheel buttons and Cruise Control activates on my dash, just does not set or cancel due to the missing 4 pin switch

      Hi Guys
      Changed the thermostat in my 2002 B4 Legacy this morning.
      Noticed bubbles coming from the overflow.
      The car isn't over heating, coolant isn't boiling, A/C blowing hot air as it should, Thermostat definitely opening, Oil clear and clean.
      Going to be replacing the radiator cap and bleeding the cooling system again with the front jacked up this time, did it on a hill the first time hoping it would have the same effect.
      Any other ideas of what it might be or things to try before considering the possibility that the head gasket randomly started leaking straight after putting a new working thermostat in?
      Thanks Guys.
