Early 2 Gen Wiring Diagram - Front Turn Signals???

I need a wiring diagram that include the front turn signals on a 70.

The Haynes I have omits it totally. The wires that are there are solid blue and solid white, one of each. (And there are no blue/white wire on the diagram.. at all.) I'm making a pretty good guess that one is for parking lights and the other is for the turn signal, but that would leave no ground, unless the housing itself is grounded.

If you know which wire is the turn signal and which is the parking light I'd really appreciate if you could let me know or post up a diagram.

Thanks.
