On the B18 the oil pressure switch is located in the center of the side of the block, PS. On the B20 that's where the bracket for the FI manifold connects to the block. So where does the the oil pressure switch for the B20 go. Ya know the one that connects to the idiot light on the dash?
Also can anyone tell me what the s/w larger holes are on the upper left and lower right (upper rear and lower front) on the same side of the engine - passenger side?
I will attempt to attach pics as a reference.
Thanks
