Looks like it should go here . The mounting hole pitch is correct but unsure of its function also I would have bagged and labelled any associated fasteners but I don't have them. Have trawled all the pictures on the web but can't find anything. The two small holes look as if they were for push in cable ties.
Is it this bit?

Yes that's the spot, ive been putting a pre cat sensor wire down near that area and at the time your post popped up recognised that as I've dropped my wire back through the recess in it will get a picture in morning as still have engine hatch off
Just here. Looks like cable support for the temperature sensors. The other bolt does line up it's just not been taken out yet. It could also be fitted lower down on the bell housing to help position the coolant hoses away from the exhaust. Not sure which is correct. Thanks Roy Gill after a lot of searching I managed to find another poor picture confirming this is correct. Looks like it provides extra heat shielding for the hoses and tie in point for wiring loom.
