I want to know how hard it is to install a XR-7 dash in a standerd cougar? I have a good XR-7 dash. I want the stock look with guages to monitor my motor and a tach thats why I want to install the XR-7 dash. I have been told it can be accomplished with my standerd wire harness, but Johns cougars says I must have the XR-7 harness for both under dash and engine compartment? Sory to offend all you original fans with this swap but the car has already been slightly altered with 2000 ranger purple paint, a 69 351 winsor 4 bbl and an eliminator scoop. If it makes you feel better id never modify it with anything that i cant put back to stock. thanks for all your help
