Ok, here's what I got for ya. I didn't realize it but I already posted pics of this in my gallery
I didn't get the tank bolted up, and it looks like my pictures are up to date, excpet for the front clip being back on and the tank almost being bolted on

Those are two huge closeups that will show you where to tap and how. You will see three things in the first picture:
1) The brass fitting and copper line for my oil pressure gauge
2) An aluminum fitting from S&P that is totally unnecessary (hindsight is 20/20, cost me $50 too
)
3) The factory tap (has two bolts holding it to pan) that I think is typically used for oil cooling line or something on LS-series engine pans.
Here is the sloppy description of what to do to make this connection:
* Take the two bolts out to remove that tap.
* Take a good look at the piece and notice that you can drill a hole through it - it's just casted closed
* Take a drill and drill the oil pressure tree with a 1/4" drill bit.
* Next, run a 1/8" NPT Fine thread pipe tap to thread in the sensor. (Check the thread on your brass fitting for your oil gauge ti ebsyre ut;s 1/8NPT fine thread!!).
* Screw in your oil gauge pressure line
* Drink a beer, and thank shifty
This is great way to add manual gauges. Also, to add a manual water temp gauge...

On the rear of the passenger side head, you will see a hex head bolt with no obvious purpose - need a picture of it? Look just to the right of the threaded hole at the rear of the head here:

That's it. Pop that joker out - it plugs a water passage through the head. I think it's a pipe thread - NPT10 or something ? S&P sells the adapter to convert it if you want to buy theirs - but, as with anything else from them, it's priced 3x what you'll think it's worth...After spending the gas money driving around to every specialty shop known to man and wasting the money in gas I woulda spent on the part, I finally broke down and bought it from them.
