On a 1992 Dodge Stealth Base model with a 3.0 Liter Engine It is located in the base of the Distributer, it has four wires connected to it via a molded plug. this is a source of many problems with a 1992 Stealth. The plug is located right next to the Power steering High presure hose, and on my stealth was chafed in two. It is very hard to see this problem until it is unplugged from distributer.
