Hello All,

Could someone please tell me where the body control module is in a 1999
F250 Super Duty 4x4 5.4L?  Does it have anything to do with the gauge
cluster?

Incidentally it appears that the gauge cluster does not work most often
when it is wet out. I also noticed that sometimes when it is not working
I hear the interior chime go off when I go around a corner.
I cleaned every ground terminal that I could find, but no joy yet.

I am suspecting that I am getting water in a connector, or it is loose
but I do not know where.  One time I could have sworn that I saw the
gauges jump when I released the parking brake.

BTW I unplugged the ECU and the gauges started working.  Go figure.
Obviously the gauges are independent of the ECU. According to the Haynes
manual schematics there is a Generic Electronic Module, but they do not
go into any specifics and do not list it in the index.

Plugging a scangauge into the OBD2 port allows me to read most of the
gauges (except gas and oil pressure).
