This is one good used Bosch fuel injection and or Bosch fuel pump relay 85 36 401 for all of the Classic Saab 900 cars with the 16 Valve engines made between 1985 - 1994. These relays are mounted above the fuel injection computer on the right kick panel underneath the carpet. 

There are 2 relays per car, one for the fuel pump and one fuel injection system relay per car. I tried buying new relays by cross referencing the number and the new relays did not work properly.
