it is not a cut off switch. it is a bypass to the relay for extended cranking.

what is the issue??

there is a passage above the oil filter but it is not drilled to accept anything externally.

you may be better off trying to repair the hole in the back of the distributor.

you would have to know exactly how deep to drill to get to the passage. perhaps a machine shop can help you with that info
