Welcome to ZDriver!

Are you talking about the actual gauge in the dashboard, or the sensor on the engine? And do you have the original part to re-install?

 

Put sensor in block in old sensor's location.
Mount new gauge in car.
Run wires.

 

sorry i was talking about the gauge in the dashboard...i dont know where to wire it or what to do.. thanks

 

If you're talking about the stock gauge, just put it in place and connect the original wiring. What's the problem?

 

i dont see any wirings, thats the problem and i dont know which wiring

 

download the fsm from xenon. take the electric schematic in pdf format to kinko's and have it printed on 11x17 paper. Now read the schematic and you should be able to find the wiring you need. if you can't read the schematic don't mess with any thing that uses electricity in your car or find a friend who can.

 

There should be a big connector right there where the original gauge was. If not, you're going to have to get a new dash harness.

 

Oil pressure & Oil temp. Should be a combo gauge

 

..look well. Highly unlikely someone removed it from the harness. Personally, Id swap for a mechanical gauge.

 

Anyone who runs a mechanical oil pressure gauge into the cabin of their car deserves it when they get sprayed with scalding hot oil when the feed line breaks.

Only idiots use mechanical oil pressure gauges INSIDE THEIR CAR.
