Not sur eif this is any help, but these are the parts I used to make an ibus socket to two ibus plugs. It took some time at the dealers to get the right parts.

B61.13.6.931.929 Pin Terminal (connector to accept ibus plug from CD)
B61.13.0.006.664 Pin Contact (3 of these connect into above to make a lead)
B61.13.8.377.072 Plug (Same as ibus plug - I used two of these)
B61.13.0.006.663 Term (3 of these go into each of the plugs above - I got 6 of these)
