MReid,
I attempted to pay homage to the below pic of 1076. If you look up the string a bit to the shot where the rear clip is opened up. There is a notch on the LH side (wrt vehicle) where the switch will sit. Visible, yes, but not outside of the plane of the body surface. Not aware of an external fire system release on 1076.
Thanks Bill. Yea...yea... will do...
