So use eol
If two pirs are linked they probably only using power shared and a pair for one PIR and a pair for other PIR , that's your six , provided the six core is the one going back to the panel
So remove the tamper pair , and use one pair only and use deol , get resistors that match the panel , I think they might be 2k2 and 4k7 , can't remember exactly
That will leave you a spare pair at each sensor, maybe why you were confused dot com
