Guys, can I run an oil pressure gauge on a 77.5 924 using the existing oil pressure switch? I suppose I could just go out and look at the switch and count the contacts, but this is warmer

The 931 pull-apart is going slowly but surely. I'm hoping for some decent weather - it sucks pulling cold wrenches. And I may try to get a camera so you can all look over my shoulder at the goings on. And on. And on...

Thanks in advance for an answer to A) above.

If the car originally came with a gauge, it would have the combo oil pressure light switch + pressure gauge sender. If not, it would only have the pressure switch. Might as well take a look, but you should find it's the single function switch.

Thanks, smoothie,

If I find the single-function pressure switch, I should be able to replace it with the dual-function one and fun the gauge, no? The location and threads will be the same?

Yes, same location and I'd have to give it a 99.999% certainty that they're the same thread size. It just wouldn't make sense for them to use different sizes on those pieces.

Fun-easy project for when the engine (or at least the head) is out of the car - virtually to literally imposible otherwise - http://pg.photos.yahoo.com/ph/smoothies931pics/detail?.dir=bdb3&.dnm=a835.jpg&.src=ph
