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.

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.
