Not needed if optional Banks iQ is 
installed.
CAUTION: Do not use force 
when working on plastic parts. 
Permanent damage to the part 
might result.
1. The Six-Gun switch will be installed 
on the driver’s side of the instrument 
panel (IP) next to the steering column 
(see Figure 10). Carefully remove 
the IP from the dashboard by slowly 
pulling outwards from the dashboard 
around the edges of the IP, allowing 
the mounting pins to pull free from 
their dashboard sockets. Automatic 
transmission equipped vehicles will 
need to set the parking brake and 
move the shift lever down to the 
lowest gear to allow clearance for 
instrument panel removal.
2. Cut out the supplied template 
(see Figure 20 on page 27) and align 
the template onto the rear of the IP, 
squarely seating it on the top of the IP 
mounting pin (see Figure 11).
3. Using a 
3
⁄8” Uni-drill bit, center the 
bit onto the 
3
⁄8” drill location on the 
template and slowly drill through the 
IP. Using a 
1
⁄8” drill bit, center and 
drill through the 
1
⁄8” location on the 
template. Remove and discard the 
template and any plastic shavings.
4. On the front side of the IP, align 
the Banks Six-Gun label onto the 
previously drilled hole (see Figure 12).
5. Remove the nut and internal tooth 
washer from the Six-Gun Switch. 
Rotate the shaft counter clockwise 
until the shaft stops. Verify the locating 
washer tab is inserted into the #6 
position on the switch (see Figure 13).
NOTE: If the washer is in any position 
other then the #6, your Six-Gun Diesel 
Tuner will not select power levels 
properly.
6. After confirming the locating 
washer is in the #6 location, install the 
switch through the 
3
⁄8” hole on the 
backside of the instrument panel. The 
alignment pin should rest in the 
1
⁄8” 
hole and with the switch fully rotated 
counter clockwise; the shaft’s flat side 
should be facing the steering column. 
Secure switch with internal tooth
