Oil Pressure Switch

Can anyone tell me where the oil pressure sending switch for a '90 acura integra 5sp hatch is located. Trying to change the thing and I cannot locate it.

Thanx in advance

i could be totally off on this since you have a teg engine but, on my '00 EX engine it's above the oil filter. it think it's gonna be something you will have to feel for. jer replaced mine for me and pointed it out...but my car was up on a hoist. i think if i were laying on the ground looking up under my car it would be hard to see.
