I receive many emails asking about the GND
connection, in reality it is very simple, you use some kind of a clip so that
you don't have to hold it in place, you DON'T HAVE 3 HANDS and there are 3
connections, GND SDA and SCL, so have a clip for GND, then you can use the 2
hands YOU DO HAVE to hold your SDA and SCL probes in place.
Almost any large piece of metal or the screws
for the external connectors of any ThinkPad are a good GND connecting point.
Anyway a picture is worth a thousand words

Basically
you make the System board functional outside of it's case which includes
mounting heat sink and fan on CPU.
Once
you have taken care of the GND connection.
You
push the sharp probes onto SCL SDA , this is the reason you need 2
persons, not enough hands to hold the probes and run the software.
This is not easy, you will need to have the Keyboard [and
optionally the LCD] plugged into the system board in such a way that none
touch any contacts on the system board, use paper as an insulator to keep
things from electrically shorting out, later you will need to plug in the AC
adaptor and switch ON the TP, then you will need to hold 2 probes in place to
the SCL and SDA points on the system board.
See my page on Options
for Clips and Probes including making your own probes.
This page ONLY describes how to connect the
KeyMaker Interface to the EEPROM.

a Supervisor password are in The "User's

Assembling your TP - AFTER - you have finished.
Follow the Hardware Maintenance Manual [FRU System Board],
very carefully, double check screw type and size for each individual module.
Assemble the TP in the reverse order used to dismantle it.
