Which oil pressure sender position is normal? does it matter?

Hi guys.



I came along this pic and thought hmmm.. something's different.

My oil senders are in the reverse position of this motor? Which is normal? Does it matter? It shouldn't matter right?

Thanks
Josh

They are normally the other way round on 3B and ABY engines. Big (pressure gauge) sender at the top and smalll sender belowso yours is correct.

Shouldn't matter as the low pressure sensor (white one) is in different mounting in non sport package cars (ie no pressure gauge).
I mean N/A 90's and such.

Bringing an old thread to life..

What about the wires on the sender, does it matter if they are switched?
I've just installed a new sender and the design was a bit different from the old one. Instead of the terminals sticking out like on the old one, one pointed up and the other down. So I just had to guess were to put each of the cabels.
Now, when I start my car the oil pressure is off the scale. 5bar++.
Just had the engine rebuilt with new oil pump etc, and only started it and had it run for a couple of minutes yet. But I did notice the high oil pressure, prior to the rebuild I could not get past 4 bar on idle.
So now I'm wondering if this high oil pressure is a positive effect of my rebuild or a negative effect of me putting these cables on the wrong way around.

No worries!
The oilpressure dropped to just above 2bar whan the engine had heated up, that's about right at idle?

Well I just found out the hard way that the AAN big sender is a different part number than the S2 unit. It also has a larger diameter thread.

S2= 035 919 561
AAN= 034 919 561

I could use this in the upper location but then the other (small) sender wouldn't fit below

Efini@ its coreckt oilpressure....
i will have som higher....,but its NOT bad..
the tuner say: ca 1 bar pr 1000 rpm, but NOT over 7 bar oilpressure.. 2-5 bar oilpressure; its perfeckt
