I'm feeling a little dumb now...
I swapped a 1.6TD into a suzuki samurai. Part of the swapping process is to put on an angled oil filter housing from a fox? I screw in the samurai oil pressure switch on the filter housing and plug in my wire.
The samurai low oil pressure switch will fault to ground turning a light on in the dash when it sees pressure under 2-7 psi.
Well, my pressure switch was leaking oil. This got me to calling around to parts places to find a replacement. This got me to asking about different pressures etc. and this is when the realization hit me that by placing the samurai switch in the VW I could be starving my motor and never know it. Specifically when they told me the VW switch trips at 18-23 PSI
I get on here and do a search. I already knew that the 1.6TD has two switches. One on the head and one on the filter housing. One is a high pressure switch and one is low. I think the one on the head is a low pressure switch and the one on the housing is high pressure?
It does make sense that the one on the head will read a lower pressure. Does that fault to ground?
Does the switch on the filter housing fault to ground?
Looking for an overview of the stock oil pressure switches..

Excellent!
That clearly answered my question as to how the switches work.
Now to try and adapt to my application...
I could just hook up the low pressure switch on the head and leave the one on the flange alone. This will give me the idiot light on the dash.
I could connect the idiot light on the dash to the switch on the head and find an aftermarket guage for the flange. Problem is finding a spot in the cab to place it. Space in a samurai is almost nonexistant....
Any other suggestions?
Earlier MK1 cars only had the switch in the head for the idiot light, so that should be adequate.. IF you are thinking about a gauge, personally I would also connect that at the head since that is the last thing in the system to get oil.. Although not real probable, it is possible for "whatever" to happen that you would still have pressure at the flange and nothing to the head...
