I coverted my truck from gen to alt recently. I bought the 80 amp alt from Patricks. It comes with DA plug. One wire (red) from plug to goes to stud on the back of the alt and the yellow wire you can connect to the S side of the starter selenoid. There is bump in the DA plug which cuts of the electricity to your starter and turns of the engine when you turn off the key. Battery is charging and running normal
