I think a lot of those has been bypassed and now use the Emegerency shutoff
(in the middle of the dash). There is also a box on your engine side
firewall that could/will cause trouble, it's up high on the driver side and
one big cable/plug going into it. When it goes bad the engine stops. It's
repairable and there was a article about it in the MV magazine. Maybe
someone will remember more. Wayne
