Motor I'm using for my s52 swap is from a 99 M Coupe. Real OEM diagram shows 3 tapped inserts coming out of the cylinder head. Two are for sensors, and the other is a coolant port that runs to the throttle body.. On my cylinder head, I only have two ports. I was going to use one for the cluster temperature sensor and the other for the OBD2 temp sensor. I need a third port to run the coolant line to my throttle body. Those of you running OBD2 on your swap, what did you do for a third port solution? Not really sure why my head doesn't match the diagrams online.
EDIT: never mind, ended up deleting the throttle body coolant circuit. now using one port for cluster temp and the other for head temp sensor...
