On the 90-93 Integras they have the Cooling Fan Modual that will run the cooling fans with the key off. I don’t remember all of it but i know one of the sensors it looks at is a Oil Temperature Sensor that is a Green 2pin Connector next to the stock oil pressure sensor and water temp switch. It looks to me like its in the center of a plug that caps off the holes that the Turbo B-series guys use for the catch can. But that might be a difference in Vtec vs Non-Vtec.
My question is if anybody knows if that sensor sees pressurized oil aka in a oil galley. My motor is swaped and doesnt have any of the cooling fan BS and i would like to run a aftermarket oil pressure gauge. I figured insted of buying a Oil Filter Sandwich adaptor or making some SS Hose T-fitting deal to tap into the hole for the stock oil pressure sensor. Id just run the aftermarket sending unit in that hole.
