Wiring diagram for '95 lumina?
I need to know where I can get a diagram for the wiring between the ECM and the dash temperature gauge on a '95 Chevy Lumina, 3.1L. Or, if I put an after-market temp gauge in (cause mine is broken) will it mess something up since there is nowhere to plug in the plug for the temp sensor?

You have two sensors.One in the intake manifold by the thermostat.It is for the computer.The other is in the corner of the rear cylinder head on the drivers side just below the valve cover.It is for the dash gauge.It has a single green wire.Unplug the connector,turn on the ignition to the run position,ground the wire and see if the gauge moves.If the gauge moves,the wiring and dash is ok,replace the sensor.Those gauges aren't accurate so don't be picky if its off 20 degrees.
