need to know what wires I need to hook up this inverter to for these dash gauges.

 

switched +12v and ground.
the bulbs that light up the dash is a good start.
there's plenty there to choose from so just be sure that you don't connect to a constant source or else your new gauges will have a much shorter life span.

 

Sorry to cramp your style rizz but STOP RIGHT THERE. The inverters that come with these kits usually have there own dimmers. Read the directions carefully. If you connect these to a light on the dash you could short out the converter because your dash lights have a dimmer. It is very easy to open up the light switch panel and take the running light lead as your power for the lights. You can remove most of the bulbs on the back of the cluster but certain ones (it's been a while) need to remain to backlight the boost, oil press, and a couple of others.

 

yeah you're right.
I shoulda thought of that.
I was just thinking about the one that i have. It doesn't have a dimmer, just on or off.
