will be using an FT817 and/or FT857 (same connectors)
I don't have an icom at all, so make sure to keep that connector
I have an extra 6-pin mini-DIN to make the cable, so
should I wire it up the signal link for the FT-817
that way when you get it, it is all set to go for your Yaesu,
will do that if that sounds good to you (I understand if you want to wire it yourself, and just mail the new connector with it )
it kind of sounds like you might have a nice connection that works with your radios already, so you might want to keep them intact that way,
I can make the connectors I need pretty easy
so whatever you want is good with me.
I might be over thinking this,
looking at the IC-703 mic connector, it looks like a short ethernet connector would work to the signal link,
or maybe better a straight through 8 pin to 8 pin modular connector,
depending on what one you use I think you might have to wire the Yaesu connector to match the internal jumpers to make sure you don't have to change the internal jumpers when you change radio connectors...
would you like anything in addition from my direction, like the antenna that I messaged you the details on, or an MFJ-260C (I have made contacts using it, but never more than a mile away), also have other small things if you are looking for anything else
