I have a 79 LeMans, it has the idiot lights for the water temp, oil pressure and charging system. I recently came across a 80's Bonneville that had the gage package in it. I'm wondering if the gage package will plug in where my idiot lights are at. I know it will require the sending units for the gages. I'm concerned about the basic wiring in the dash. Been looking for a Chiltons Manual for this car to look at the dash wiring but they are hard to locate. The arrangement of the gages are the same as the idiot lights - just wondering if I could just remove the idiot light cluster and plug in the gage cluster and everything work. Sure would make things simplier. CJay
