What gauges, and where did you install them?
Pictures would be helpful. Some members have installed them in the upper dash vents. I can't help you on the wiring because the 06 has backlit gauges.
Well, those details don't really effect the info I need, I know how to wire up all the rest very easily. With the 2009 M/Y (maybe earlier) on going just about entirely digital for everything in the car, finding the correct circuits has proven difficult.
3 Autometer Z Series Short Sweep Electric Gauges, on the top left of the Dash, pressed up against the A pillar, in line heading inward.
Trans Temp Gauge
Oil Pressure Gauge
*Power, all three wired in parrellel, need to find an Ignition Switched Source to splice into.
*Ground, all three wired in parrellel, will ground to the Engine Block.
*Sender Oil Pressure, will connect to the Autometer Sender.
*Sender Trans Temp, will connect to the Autometer Sender.
*Backlight Power, all three wired in parrellel, need to find an Dash Light Source that the voltage/power varies with Dash Light Level.
I don't think I can find one (because of the way the Digital System handles LED Backlighting) and may have to settle for the source I've found, that just supplies system voltage when the lights are turned on.
*Backlight Ground, all three wired in parrellel, connected to a metal ground under the Dash.
