Mopar Forums - Help to identify this part

I sent my heads in for machining this winter on my 09 Ram 2500 XLT with the 5.7 Hemi. I have them bolted back on but can't seem to find the purpose for a plastic clip that mounts in the rear left (drivers side) cylinder head. It has two Christmas tree fasteners that slide into the the holes that are where the EGR would be connected (were it on the front and right side). It looks like it is a black plastic slide about 1 inch long, possibly for a wire connector. For the life of me I am not finding any plugs back there that would attach to that piece. Any one had experience working with these Hemi cylinder heads and found that mount on the back facing the firewall? It is not a cheap zip tie/band type of mount, it is meant to hold something solid (Thus my worry)
