Well I'm chasing it and I'll post on here if I figure this out ...
Update , last night I reinspected my entire install of the Lin Bus circuit as follows : visually inspected pins & sockets wire conditions, tugged on everything to ensure good factory crimps and seating ect..ect...
Figured out the purple wire in my OEM Harness changes colors @ the tailgate disconnect to a orange and dark blue stripe , (just like up front @ BCM C-5 / 45 Connector ) this wire changes colors again @ the next litle short camera harness @ the handle assy inside the tailgate to a much smaller diameter light blue wire ,maybe 22 gauge or 24 any how I was able to ring out every wire in that new short camera /Tail Gate lock harness AND THEN I HOOKED EVERYTHING BACK UP / WITH THE EXCEPTIONS @THE C-5 CONNECTOR AND THE TINY SLIDE ON TYPE CONNECTOR AND VERIFIED CONTINUITY FROM THE FACTORY INSTALLED SOCKET 45 ( FRONT SIDE ) AND THE TINY , TINY UPPER CENTER SOCKET ON THE CAMERAS SLIDE ON CONNECTOR !! I WAS USING MY CALIBRATED MULTIMETER FROM WORK AND A 65 FOOT 22 GAUGE WIRE LOOM AND THE TOTAL RESISTANCE WAS 2.3 OHMS !
That's a good low resistance for a 65' loom and the entire OEM harness assy 20 + feet with 3 connectors and my solder joint @ the Orange &Dkblue Blue wire socket 45 , C-5 Connector . Oh and I verifier the BCM DID HAVE a male pin @ this wires location LOL ! wouldn't that be a hoot if it was blank . I have no way to troubleshoot beyond the BCM Yet , I'll be trying to obtain a more detailed wire diagram soon and updating my Radio RA2 Software soon as well .
For what it's worth , still no active lines !
Anyone who has a working knowledge of the Lin Bus system and clock spring detailed attachment to it and any knowledge or suggestions of an a curate way for me to troubleshoot beyond the BCM. , To figure out why I do not have the Active grid lines on my 2014 RAM Q.C 4X4 1500 ST , With a newly installed OEM Tailgate camera backup system I WOULD BE ALL EARS FOR SOME ASSISTANCE. ..THANKS IN ADVANCE!
