There is loads of posts about where to mount an oil pressure sender to larger engine cinquecento but not a clear answer to where to mount it on the smaller 899cc engines. dose anyone have experience of fitting one and the best place to run the wiring into the car?
the original oil pressure switch location is on the back of the block about central height 2-3" back from the gearbox either that or get a sandwich plate for under the oil filter using fittings you should manage it
make sure everything is tight or you will destroy your engine in a few minutes
