I am putting together my 67 charger dashboard and I have all of the wires connected and found this relay labeled signal stat and I don't have a plug for it. Does anybody know if this is an option or is this a necessary relay that I need to have plugged in? I guess if it's called a signal stead it must have something to do with my turn signals but I'm not sure. Anybody can help me I would appreciate it. It is located under the glove box.
