Could someone help me understand what to do to connect a new four wire wiper motor to an old three wire system, and how to install a diode.
I just bought (ouch!) a new wiper motor from Alfaholics for my 69 Series 1 GTV. The old motor was frozen. The old motor had three wires: red, white and green. The new motor has four: blue/black, blue, grey and blue/white. The new motor came with a diode and a wiring chart. The chart shows the diode attaching to the blue/white wire and then running to the grey wire. This two-into-one combination then takes the place of the old green wire. But, I've never attached a diode before. In fact, I don't even know what they do. The diode has two prongs at the bottom and a metal plate at the top with a hole in it. It looks to me like I cut the blue/white wire in half, attach one end to one prong of the diode, the other end to the other prong and then splice the blue/white to the grey. This would mean that the diode serves as a bridge between the flow of electricity through the blue/white wire before that wire connects to the grey. But before I go hacking up my new motor, I thought I'd see if anyone can give me some direction.
Thanks. Tim
