I need to splice a square plug onto the round alternator wires on my Gen 1, so I can use a square plug alternator. The problem is that the original plug has more wires, and they are of different colour combos, so I have no idea what ones to splice together.This is a pic of the round plug wires:


And this is a pic of the square plug wires (note there are only two wires for this plug, there's just two plugs together in this pic):


Hopefully someone out there knows what I'm on about and can help!
Thanks!
