The oil pressure sender is on the front part of the engine (as it sits in a 914), on the driver's side, plumbed into the cam oil line that runs up and over the timing chain housing. The oil pressure switch is on the top of the engine, next to the breather cover, aft, near the centerline of the case. There are two oil temperature senders, one for the gauge, the other for the FI. The gauge sender is just below the oil pressure sender, forward. The other sender is on the passenger's side timing chain cover.
