shielding for pip and saw

HI ,i have progressed to the point of making the cable from M.S 2 V3 to the relay board and i am using EDIS i have put in a shielded 2 core wire as an interconnect however where can i connect the shield too in the db37 ?, is there a spare earth pin i could put them onto .
the wiring diag in the manual shows picking up the earth at the edis module but that wont shield the relay cable as it doesnt connect thru the db37, secondly ,picking up an earht at the module creates the possibility of an eth loop so i would much rather use the same point throughout.
so in essence is there a spare pin connected to ground or a spare pin i could jumper to gnd in the ecu so i can have a thru connection of the same eth potential
i hope this makes sense
thanks in advance

Pins 2 and 7 - 19 are all connected to the same earth or did you mean over and above these?

Thanks Phil
I have run pins 7-11 inclusive and pin 19 as indicated in the manual ,so if pins 2-6 are also connected to the same eth then i can use any of these ,am i correct in saying this ?? It would also stand to reason i could add a couple of extra eth wires just for security on pins 3 4 5 &6
thanks

Nope!!!

Pins 3 - 6 are for the "spare" strap holes and are not connected to anything unless you strapped them to some in- or output on the board. But you COULD then connect these pins to earth as well by strapping those "spr" holes to earth if you have no other use for them.
