Ok...I have a 74 2.0 that the high beams stopped working on. I checked things out and hopefully determined that the dip/dimmer switch was the culprit. Ordered a new one that arrived today. It has an extra terminal on it. when making the usual connections per the old switch on the new switch, it does not work. What or how should the new switch be connected....do I need to make a jumper to the new terminal?
