The high and low pressure sensors have different switch operation. Low
is normally closed, opening with adequate pressure. High is normally
open, closing with adequate pressure. If two high pressure sensors were
used, response would be as follows"
Engine off, oil light off,
Engine on, light would be flashing as soon as pressure is made.
Engine over 2,200 rpm, Light still flashing.

I have seen this problem with two of your options.
One of them is the reversed senders.
The other is two of the upper senders were used.

Assuming the circuit was the same as on jetta/passat et al.
