can a 93 oil pressure sensor wire be converted to a 95 unit?
My 93 broke when i removed the engine, the replacement LT1 is a 95 and has it still attached.

What is the Wire Plug in the tail shaft of my 93' 4l60

What is it, how important is it?
The wires got pulled out of the plug when i removed the engine.
I will buy a pig tail later but i want to crank and test drive the new engine.

Answer: NO, the sensor is different inside. It will give you a false reading
But Yes, the pigtail is the same.


On a 93 z28 The oil pressure switch/sensor is connected to the Fuel pump, no oil press. the fuel pump will turn off.

not too sure about the sensor,i do know the instr.clusters are different and will not function properly in a 94-97...
the wires you pulled out are for thr VSS(vehicle speed sensor)you will want to repair that so your speedo will work and the transmission will lock-up....

what do you mean by lock up?????


and does the ECU require the oil pressure sensor be working for the engine to run properly?

when your car goes into 4th gear you will notice shortly after the gear engages the RPM will drop an additional 2-300 rpm that is (converter lock-up)....

The oil pressure sensor should not be a problem and the computer is not fed oil pressure information.

If you use the 95 oil pressure unit you will also need the 90* bend. The plug that is on the top of the block should fit where the 93 oil pressure unit goes. I can't remember if the pig tail is the same but I think it is, just remove the rubber cover.

I went to auto zone with the old one in my hand and mactched it up. I don't remember exaclty how much it was but i want to say around 20 bucks. I broke mine when putting in my long tubes.

the rebuild engine is a 95 LT1 and has all the stuff i just wanted to know if anyone had been able to convert it the wires.

But if they are that cheap at auto zone ill just buy a new one. my 2nd water temp sensor also snapped off. WTF are these bastards made of.

I pulled back the stupid rubber thing and there is a plug under there. Who knew. I thought it was on big unit. I unpluged it and it does fit the 95' once i get it started ill tell u you if it works. Im haveing a no start issue and the gauge goes all over the place when i starting it.
