HI Wayne..
i am trying to find out which thermostat housing is the right one. one has two temp sensor holes and one has four temp holes ..they both say from 87 to 91 325i models..but which is the original car that came with the two temp holes on the thermostat.. i have a 90 and a 87 engine somebody changed a thermostat on the 90 and has four temp holes on it. and calls for the 2 temp holes housing.. i am confused .. please help as i cannot find any wire that goes to the two extra temp sensor that they have on the housing.... thanks again

You probably only use the two hole housing. Plug the other two holes. You can also call one of our parts specialist at 888 280 7799 to verify you have the correct part.
