Switch... 70 and laters

Cylinder, 71 and laters... 70 and some earliers 71 got a diff locking setup on collar for the cylinder

Need to note several replacement switches are made now to match several setups, so will need to match your one ( remove one extra black wire they got for example your Chally doesn't use ). Some manufacturer include instructions sheets, but some others not.
