oil pressure switch

[turbobuick87gn]

i'm new to buicks just bought a 87 grand national. the car came with autometer oil pressure gauge, that is not hooked up and i'm trying to install it this weekend. my question is this..where is the oil pressure switch located on this engine. is it one the back of the block like a sbc, or is by the oil filter housing. and help will be really appreciated.

Above the oil filter on the passenger side of the front of the block.

 

["Turbo-T"]

You should see a brass tee fitting where the turbo line attaches to it, there's also an electrical switch in there for the fuel pump relay. You'll have to remove the switch and get yourself a brass L fitting and put the switch in one hole and the gauge line in the other. HTH

Or add a "T" & you can use all three then.

Or juist drill and tap the stock brass block for a clean install

I did what Blown&Injected suggests, and it works very nicely.

The oil pressure(idiot light) sender and fuel pump bypass switch are the same unit. It has three terminals on it. Don't get confused, looking for two different switches.

Three as in the switch, the new guage line & the turbo feed line. I wans't very clear but he got it figured out with the tap. I just find the "T" easier but his way is cleaner looking. Glad its working!
