I pulled out my FT1000MP manual and studied the pinout page for 
the band data jack. It's difficult to describe, ONLY because the 
mfr of the plug uses a crazy, illogical numbering scheme for his 
plug. Not only that, but the numbers are VERY hard to read. So 
I'll dispense with numbers, and start from scratch. Realizing it's 
nuts, Yaesu does not number the pins, they simply point to the 
pins and tell you the pinout. 

Yaesu gives you a graphic of the connector, and the caption says, 
"as viewed from rear panel." The gap in pins is down. This is what 
it looks like on the rear panel as you look at it from outside the 
radio. In order, clockwise, starting from the gap, the pins are:

Band Data D 
Band Data A
TX Gnd
Band Data B
TX Inhibit

The center pin is Band Data C

BTW -- the numbers printed on the actual plug are, in clockwise 
order, 6, 1, 4, 2, 5, 3, 7. The center pin is 8. AND, the printing 
of the numbers is SO light and so bad that depending on how you 
look at it, they look like different numbers. 5 looks like 6, 6 
looks like 8, etc. AARGH! 

Another point. When I bought a stock of DIN plugs several years 
ago from RF connection, they asked which version of the 8-pin I 
wanted. There are two. One fits Yaesu, one fits other radios. The 
location of the pins is different enough that they don't mate. 

Another problem. I've bought plugs like this from more than one 
source. Most of those plugs MELT when you try to solder to them, 
even with a very good temp controlled iron. AARGH! One solution 
I've seen is to plug the plug into a mating jack while you solder
