The least expensive option is the manual "T handle" tool. This tool
works OK for terminating small numbers of MTA IDC connectors by hand.
Some people seem to disagree on this but I say, if you take a minute
to figure this tool out, it works a ∗lot∗ better than a flat
screwdriver. You still need to clamp the connector in a vice when
terminating the wire but, again, this tool will produces better
results if used properly. This tool is under $20.
T-Handle tool for MTA156 connectors (MOTM power)
AMP (manufacturer) part number 59804-1
Digi-Key part number A9981-ND
Mouser part number 571-598041
If you need the smaller MTA100 connectors for any reason (for example,
I think these are used on "dot com" modules?) the equivalent tool is:
AMP (manufacturer) part number 59803-1
Digi-Key part number A9982-ND
Mouser part number 571-598031
The next step up is the "pistol grip" crimp tool - and it will cost
you about 10x to join the club. (You have to buy the "crimp die" and
the pistol grip frame as two separate pieces, which totals about
$150.) The nice thing is this tool holds the connector shell for you
and there is a little slot you feed the wire into. Squeeze the
trigger and the wire gets pressed into the connector and the connector
shell advances to the next terminal position automatically. This
tools works good enough for "limited production run"
The pistol grip frame part numbers:
AMP (manufacturer) part number 58074-1
Digi-Key part number A2031-ND
Mouser part number 571-580741
The die set for MTA156 (MOTM power connectors)
AMP (manufacturer) part number 58247-1
Digi-Key part number A1999-ND
Mouser part number 571-582471
The die set for MTA100 (if you need this size)
AMP (manufacturer) part number 58246-1
Digi-Key part number A1998-ND
Mouser part number 571-582461

As I recall (from a phone conversation) Paul has the power cables made
to order. The place that does this work for him terminates the
connectors on a fancy machine. (Some of these machines actually use
the same "die set" as the pistol grip tool but the manual frame is
replaced by a machine cycle.)
Paul does have power cables available on the official MOTM order form
- if you don't want to build them yourself (or don't want to invest in
the tools) you could always just order extra cables from Paul.
