Where is low oil pressure switch on a 1967 Pontiac trans am with 400 engine?

The exact location of the low oil pressure switch on a 1967 Pontiac Trans Am with a 400 engine can vary slightly depending on the specific engine block casting and any modifications. However, it's almost always located on the engine block itself, near the oil filter.

Look closely around the oil filter and its mounting area. The switch is usually a small, cylindrical device with one or two wires attached. It might be mounted directly to the block or on a small bracket nearby. A shop manual specific to your 1967 Pontiac 400 engine will provide the most accurate location. You can usually find these manuals online (eBay, Amazon) or through Pontiac car clubs.
