I got a new speedometer, but the plugins don't fit, so I'm just going to connect the wires directly, I know what wires do what on the new speedometer, but which wires are what that just got unplugged from the old speedometer? There are 2 plugins that go to the old speedometer, I need to know all of them, hope this isn't too much to ask, I am searching as this is here. Thanks for any help!
