FINDING YOUR COMPUTER
Ford
-- ATTENTION
: The 3 or 4 digit alpha numeric values are
what we need to build your chip. This information is on the connector
end of the computer
above the UPC bar code. Here's a more
comprehensive list
link and some pictures of example labels showing the information we
need.
The computer is
a large
silver box with one large rectangular connector of 60 to 120 pins. Truck
computer locations vary from behind and left of the park brake bracket,
to the passenger side kick panel or above the right side kick panel. Car
locations vary from under drivers' dash, passenger kick panel, and above
and rearward of the glove box. Prior to ECU removal:
1st. Remove the
ignition key from the ignition cylinder. Disconnect the battery negative
terminal.
2nd.
Disconnect the main connector with a 10mm
socket from the firewall/bulkhead side and gently slide the connector
away from the computer.
3rd.
Remove the computer-- in most gas trucks
from above the passenger side kick panel after the plastic retaining
clip is removed, the computer will almost fall out. The 1998-2003 Diesel computers are inside the black
plastic sleeve near the park brake bracket. We now mainly
concentrate on 1996 and up Ford products and no longer support the older
models other than some of the older Mustangs. With our DPS-FORD system,
removing the computer is no longer necessary as we can reflash the
computer directly.
The 1996-2007 Ford codes are directly above the UPC stamp on the
white label which is glued to the ECU
connector, and on a black plastic cover on the computer J3 port. Ford Codes are always
3 letters and one number -- ANY OTHER NUMBERS are not needed for your
order, unless mentioned on the order page.
Chevrolet
and General Motors
Computer
locations vary...
1987-1995
GM Truck computers are always behind the glove box
(4.3, 5.0, 5.7, 6.5 TD, 7.4L). Look for a silver box with two or 3
connectors. The computer often has a white label which indicates
computer service number and 4 letter code. To verify the code, always
remove the computer cover (two 1/4" screws) and note the label directly
on the computer chip.
Most if
not all the Astro Van ECM's are behind the right (passenger) kick panel or under the
hood (after 1995).
1984-1988
Pontiac Fiero computers are located rearward between the seats.
1982-1995 Car
locations vary from behind the glove box, above the glove box, under the
passenger side dash, under the
hood at the right strut tower, the right side kick panel. 1995-1995
Cadillac is always under the passenger side dash.
The computer code is always 4 letters on the computer
white label tag (Service # 1227747 code
ANLW).
This code is required for all 1982-1995 GM computer reprogramming--as we
always prefer to work from the original calibration rather than supply a
'generic' one size fits all calibration.

larger list of
locations and
instructions for PROM and MEMCAL removal and re-installation.
Once you find your
1987-1995 GM computer, locate the box "code" -- and

1996-2007 Computers (VCM/TCM/PCM) are
normally located under the hood, except in the case of some V6 cars
(under drivers' side dash).
