If I recall correctly, it was unclear where the proper location was for 69 and maybe 70. I elected to drill a 3/4" hole with a Rotabroach cutter since the harness had a grommet attached. However, the hole location shown in the picture in post 1 is not correct . Here are links to some threads regarding hole location and size in case you decide to drill a hole.

Thanks I seen those posts but I missed the one by lockdoc. I am currently filling the holes on my fire wall and wanted to have the correct tach hole. I am going to just run it with the oil line then.


Thanks for the quick responses
