I have been asked to post a little about my rewire of my Crown car
The original wiring In my car was marginal at best so I modified it to a more modern standard and functionality
I use a lot of the advice and recommendations found at http://www.madelectrical.com/
I find this site to be great for most of the ills of our old cars and it saves the brain damage of a total rewire in general the factory wiring system is best for all cars basic needs,
as you add options a simple addition to the stock system is better than a redo of the whole car
I modified my charging, lighting, and starting system in the stock harness and for my additions I added a painless 7 circuit panel to my car and still have the ability add more with little or no hassel
if you have questions feel free to email me and ill try to assist the best I can but seriously read through the information at http://www.madelectrical.com/ you wont regret it
I have used the same type of system upgrades to most of my Buicks as well so I know these work and work well
