The can be time consuming but there not too hard to do....
I have a triple pillar w/ Volts, Oil Presure, Boost/Vac...
The Volts required:
-12v switched power
-ground
-12v dimmer power for lighting
-ground for lighting
The Oil Pressure required:
-12v switched power
-Wire from gauge to sender installed on the motor (Electric)
-ground
-12v dimmer power for lighting
-ground for lighting
The Boost/Vac required:
-12v dimmer power for lighting
-ground for lighting
no other wiring due to it being mechanical (used a vacuum line hooked up to the motor)
There you have it.
Another thing I highly recommend you doing. If you get the Autometer gauges the stock clear blub in them makes the color a white/yellish color at night a simple and cheap fix (under $5) is go to you local parts store and get a 194R blub which will be red colored blubs. IMO they match the Grand Prix red lighting interior perfect! You only need 3 blubs and they take less than 20 seconds to replace. Some guys mess with LEDs and such, thats up to you. So far my setup has worked great for years...
