Fitting
a Powerchip Ford EEC Module
There are certain
procedures and precautions that you must take when fitting an EEC
module to an ECU. If you do not stick to the list below, you may
cause irreparable damage to the ECU or EEC module.
- Switch
OFF the ignition and remove the ignition key
- Remove
the ECU from the vehicle.
- Open
and remove the casing of the ECU .
- Check
if the ECU needs any links added (see below).
- Remove
any grease and/or laquer that may be on the edge connector.
- Clean
up the edge connector with scotch brite or fine emery paper.
- Ensure
that the edge connector is perfectly clean.
- Discard
the black plastic blanking plate, which covers the edge connector
- Refit
the ECU casing.
- Fit
the EEC module to the ECU edge connector (see below)
- Secure
EEC module to the ECU using tape (see below)
- Ensure
that the key is not in the ignition.
- Refit
the ECU to the vehicle.
Fitting
the EEC module to the ECU
Fit the EEC
module to the ECU as shown in the following photographs. First,
fill up
any gap between the EEC module and the ECU casing with cardboard
etc. :

Then secure
the EEC module to the ECU with tape to prevent the EEC module falling
off the ECU edge connector due to vibration :

Precautions
Do
not try to fit or remove a module from an ECU whilst the ignition
is switched ON.
Try
not apply any up/down bending forces onto the EEC module while
it is being fitted to the ECU, this will damage the connector.
Care must be taken not to bend the module on the edge connector
when using tape to secure it to the ECU.
FORD EEC ECU links
Some later FORD
EECV ECUs need to have electrical links fitted. The ECU cannot have
an EEC module fitted until this is done. If an EEC module is fitted
to an ECU without links fitted, the vehicle will not start. There
should be no damage caused to either ECU or EEC module if an attempt
is made to fit an EEC module without the links fitted but it is
best not to try it!
If
your vehicle requires these links to be made we will inform you
before processing your order just in case you do not want to get
involved in soldering!
Obviously, care
should be taken to ensure that the links are only fitted to the
correct areas on the ECUs circuit board. Links fitted to any other
areas of the circuit board may cause permanent damage to the ECU.
The links are
made by
- Identifying
the section of circuit board to fit the links to.
- Removing
any laquer from the circuit board pads.
- Soldering
lengths of wire from one pad to another.
There are 4
pads which are of interest, these should be connected as shown in
the picture below. There are small variations in exact location
of these pads, but they are all roughly in the same place, on the
underside of the printed circuit board. The links are always made
left to right as shown.
