External ATU with IC 706

Jim's mail-2
At present, I do not yet own any Elecraft items although several of the
Elecraft items on the web site do interest me.  The primary reason for this
message is for basic information.  I have an Icom 706 MK2G as the only base
HF radio.  Recently, I asked on the Icom reflector if the T1-K Antenna Tuner
would work with the IC706 radio.  The answer received was:  "Sorry, I am not
acquainted with the Elecraft product. The Icom tuners which
are compatible with the 706 series are the AT-180, AH-3 and AH-4. LDG also
make a line of tuners with the
 4-pin Molex plug interface. I believe that the LDG tuners support the Icom
tuner control scheme."

In reading the assembly manuals and the errata sheets, there is only a very
brief mention of using J1 to connect the tuner to a non-Elecraft radio.
Basic question becomes:  Is there a way to wire, or configure, a 4-pin Molex
interface on a short cable to run between the ATU and the 706?

Thank you in advance.

The owner's manual (which is separate from the assembly manual) has a
description of how J1 works.

Are you aware that the T1 is a 20W tuner? You can use it with a 706 if
you turn down the power to 20W or lower, but you will not be able to use
it at 100W.
