Installing Aftermarket Gauges

[xeroinfinity]

Here are some links for installing gauges.

The link says they are for Autometer brand gauges,
but all the info is good for any brand of gauge you might install.

Air Fuel

Oil Pressure

Trans Temperature

Voltage Meter

If you need further help post a thread in the Grand am forums and we will see what we can do

Also If you want your lighted Gauge to dimm with the other interior lights hook the positive lead of the guage light to the GREY wire on the dimmer switch.
(All grey wires in the buttons(windows & locks) are the dimmer control wire )

At the bottom of the above links has instructions for this dimmer light control procedure.
