Banks Power Ford Trucks: (Diesel ’99 - 03 7.3L Power Stroke) Power Systems- Stinger, Stinger-Plus & PowerPack systems '19991_2-2003 F250_F350 Trucks & Excursion (non-cat) - Manual (Page 17)

77.
Be certain battery ground cables
have been disconnected.
78.
Locate the engine control unit
(ECU) under the dash toward the left-
hand side of the vehicle. It will be
housed in a black plastic box bolted
to the side of the vehicle. Loosen
the bolt attaching the electrical
connector to the ECU on the engine
compartment side. This will be the
connector closest to the left front
fender. See Figure 9.
79.
Loosen the two 7mm hex bolts
on the rear portion of the black
plastic box. Remove the box and ECU
from the vehicle together. Pull the
ECU out of the plastic box.
80.
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 OttoMind
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 OttoMind engine
calibration module.
81.
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.
82.
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 OttoMind 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.
83.
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 OttoMind module over the
connector, and press firmly to set
the connection. DO NOT FORCE the
OttoMind 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.
84.
Using a band saw or hacksaw
cut a portion of the black plastic
case away allowing the OttoMind
to reside in its proper location. See
Figure 10. Reinstall the ECU with
the black plastic box, making sure
the ground tab is still in place at
the lower mounting point. Reattach
the wiring harness to the ECU and
tighten the retaining bolt. Be careful
that all the pins are aligned correctly,
as it is possible to bend the pins of
the ECU and do permanent damage!
Reconnect the batteries.
For Git-Kit installation, proceed to
Step 86.
85.
Find, supplied in the kit, the
black wire with a ring terminal on
one side and a male “fast-on” blade
terminal on the other. Install the red
“t-tap” connector on the center wire
of the MAP sensor as far from the
sensor as possible. Pull the wire out
of the convoluted plastic tube near
the top of the firewall and squeeze
the t-tap onto the wire with pliers.
See Figure 11. Attach one end of the
black wire to the t-tap and the ring
terminal end to the ground strap lug
on the firewall.
86.
Check the operation of the
OttoMind and ECU. The vehicle
