Standard Ignition Neutral Safety Switch P/N:NS-621
Standard Motor Products
Standard Ignition NS-359 neutral safety switch for the 1996-1997 BMW 840Ci and other vehicles is an electrically operated switch that restores neutral safety function. It replaces damaged OE units, is made to OE spec for fit, form and function, and tests to meet or exceed OE performance.
A car that won't crank in Park or Neutral can mean this switch is worn, though a weak battery or a failing starter can be behind a no-crank too, so those two are worth ruling out first.
It is a direct-fit replacement for the 1996-1997 BMW 840Ci and the 1991-1992 BMW 850i, and either car takes a single switch, which is what this listing holds.

Is the NS-359 neutral safety switch right for a 1991-1992 BMW 850i?
Yes. Standard Ignition NS-359 fits the 1991-1992 BMW 850i and the 1996-1997 BMW 840Ci, and a single switch is all either car needs.
Does this Standard Ignition switch come with mounting bolts or a gasket?

How many pins does the NS-359 connector have?
