i went with the american auto wire highway 22 in my dart. it has relays built in for a fuel pump and a fan plus circuits just about anything you would need. real nice kit. for the wipers and heat we rebuilt the stock connectors, ran new wire all the way to each bulb in the car, rebuilt every light socket in the car. like stated i bought a new neutral safety switch pig tail, new voltage reg pig tail and electronic ign. pig tail. everything is crimped and or solidered properly,heat shrinked everything, tons of grounds and greased every connection. i also used weather pack connectors all over the place instead of the stock style connections for stuff like the tail lights and side marker lights.
