Try these from RS:-
oops ! not allowed to post links !! (Tech Kings, you make it so easy for newbies !!)
Google RS website, 2 product codes are:-
RS Stock No. 818-700
RS Stock No. 818-693
Not sure if you need plug or socket so put both versions up. Pins are pre-wired and pushed into D9 connector, so any pin combination is possible, I have soldered links across on these before inserting pins which is also fairly easy.
RS sell to the public and have a counter in near junction 3 of the M6.
