3 wire -> 1 wire Oil Pressure Sensor?!
 

Hey guys,
Swapped an LS1 into my 2000 S10, and a nice t70 turbo on the back of it.

The engine is out of a 98 vette. It has the 3 wire oil pressure sensor.

My harness from Current Performance (made by Jared) has a single wire o2 sensor plug.



Can you connect the single wire to one of the 3 wires in the 3-wire-Sensor to make the gauge work?
I don't want to have to go buy a new sensor...

3-wire sensor has:
Grey wire= 5 volt source
Tan/wht wire=Signal
Blk = Ground


Right now, i have it Tee'd into the Tan/wht wire. Oil pressure guage is pegged (reading 100+psi) without engine running.

Can this be done? hookin it up to one of the other two wires?

Excuse me, I'm not understanding how this relates to oil pressure?

As far as the oil pressure sensors go, why not just adapt the S-10 sensor to you LS block? Then the gauge will read as intended.

Way different threads. The S10's threads are way too big. The LS block's threads are very small.

IIRC, the LS sender has 16mm threads (that's over 1/2"). Don't remember the thread size on my '96 S-10 sender, but I had no problem adapting it to the 3.8L Turbo-Buick motor that now resides there. There's likley an adapter to be had, or made... Have you tried contacting the harness maker?

just buy a single wire sensor from a gen III engine out of an older silverado. same resistance values....problem solved.

does that actually work for an s10 system
