I am trying to use an old quad jtag on the top side of my 301.013.

I soildered some pins into the ird and I know they are in the right place. I also know that:

TMS = 2
TCK = 3
TD1 = 4
TRST = 5
TD0 = 13

My question is I dont want to make my own I want to use the old quad. When I open the case to the quad there are 6 wires hooked up though not 5. there is 1 red and 5 grey. on the board inside the bd25 connector case that the wires run to the 6 wires go into 6 locations. they are:

Blue
Grn
Yel
Org
Red
Brn

how do I attach this quad to my 301.013. Thanks for all the help guys.

Cut slot out use the old quad. use 2700 setting . Takes 30min use hard board under slot cut and sharp wood chisel . JCK7

the problem is that because I'm a fucking idiot I already took the black end off the ribbon cable that plugs into either 2700 or 3100.

If I can soilder it back on fine, but I need to know which of the 6 wires goes to which of the 10 prongs in the 2800 side.
