Default ??? for L92 owners.

does anyone know if its possible to use the stock oil pressure sending unit directly with the oil pressure gauge or would i need to get that signal from the computer?

if i can get the oil pressure gauge working, my gauges would be fully functional(tach, speedo, v-meter, coolant temp, fuel)

if thats not the route i need to take, i'm open to suggestions.

Let me rephrase that.
Will the original oil pressure switch in the l92 work with the lt1 gauge?

Ok, I ran across this..

On a typical oil pressure gauge there will be three wires. dumThese wires are for switched ignition power, oil pressure signal, and ground. dumIn order to take advantage of the oil pressure gauge driver follow the gauge manufacturer’s wiring instructions.

The connector has 3 pins.
A, B, and C.

A=?
B=?
C=?

Switched power, ground, pressure signal

Can someone put these by there correct letter?

Ya know? One will be grounded at all times, one will have 5v with the key on, the last will be your signal wire. With a VOM meter it will take less than 5 minutes to get it figured...

Ok, that's makes since. So with a meter, I should set it to ohms right? And what readings would tell me which pin is which.
Ex..5V switched should read ?ohms

Ohms for the ground wire check, one test lead to ground while probing the 3 unknown wires with the other. The one that shows "0" is ground.

Volts for the 5v "key on" check. Black lead to ground, probe the 3 wires with the red lead. Whichever wire shows 5v is the power wire.

The remaining wire is the signal wire.

ok thanks. I know all the wire origins, I just don't know the pins. I have to make a Connector. The aftermarket harness has a fuse in the oil pressure switch for the fuel pump relay. I'm making a seperate plug for that gauge.

That would be in the pin-out wiring diagrams in one of the "stickies" at the top of the page, just pick one and have a look...
