RE: modifying upshift light

[drew <drew@dyermaker.cs.uoguelph.ca>]

The upshift light is controlled by a relay that gets input from a vacuum
switch, the transmission switch (so the light doesn't come on in 5th
gear,) and the tach.

The general logic of the control unit is that the light will illuminate
when engine rpms are over 2000 AND intake vacuum is between 5" and 20-25"
(roughly,) AND the transmission is not in 5th gear.  Vacuum less than 5"
would be acceleration (or working against grade, wind etc,) and vacuum
greater than 20-25" would be deceleration.

HTH,

Drew
