81.
Note the code printed on the
plastic cap on the back of the EcU.
This code should compare to the
code printed on the Banks Big Hoss
Module box label. Pry the plastic
cap from the rear of the EcU using
a small screwdriver, exposing the
printed circuit board edge connector
inside. Retain the plastic cap. The
connector will be coated with grease
and a clear silicone type coating,
which must be completely removed
before installing the
Banks Big Hoss
engine calibration module.
82.
Using a 5.5mm nut driver,
loosen and remove the six bolts that
hold the case of the EcU together.
Open the case of the ECU, being
careful not to lose the plastic spacer
or damage any circuitry inside the
EcU.
83.
clean BOTH sides of the
connector. First, clean the white
grease off with a tissue. Next, scrape
the clear silicone type coating from
the connector fingers with the
abrasive square provided.
It is very important to clean both
sides of the board in order to have
a good connection between the EcU
and the Banks Big Hoss Module
module. It is only necessary to clean
the connector fingers. Be careful not
to damage any circuit traces on the
board further inside the EcU.
84.
Orient the module so that its
edges line up with the edges of the
ECU case. If the edges do not line up,
the module is rotated 180° off. Place
the Big Hoss Module module over
the connector, and press firmly to set
the connection. dO NOT FORcE the
Big Hoss Module onto the connector,
as damage may result to either the
EcU or the module. If the module
does not install with firm pressure,
check the orientation and try again.
85.
Using a band saw or hacksaw
cut a portion of the black plastic case
away allowing the Big Hoss Module
to reside in its proper location. See
Figure
12 . Reinstall the EcU with
the black plastic box, making sure
