What do these wires go to?

[pdooley]

Well, my car built from the parts-in-trunk actually fired up and idled(roughly) for a few seconds today.
I still have lots of details to sort out, but was wondering about some snipped wires near the front of the motor.
Anybody know what these should be hooked to?

Looks like the oil pressure switch, if you find any let me know I need a new plug also.

ok, i figured it out.
Looking at the picture, i thought the pressure switch was in the oil filter housing. Not true, it is actually located in the block, inline with the turbo oil feed.
I checked this spot on my car and discovered the pressure switch was removed and replaced with a VDO sending unit. There is a VDO gauge inside the car.
