[Healeys] Wiring question

[legal_bill at verizon.net]

I asked this question twice on my aol screen name, so forgive me if you saw it and already responded.  I did not see your answer if you did.

I'm connecting the wires behind the dash and I am confused about the many ground wires.  It seems they all connect to the gauge posts to ground the gauge and complete the circuit for the dash lights.  But do any of the black wires behind the dash attach to a ground point on the chassis?  If so, where does it go?

Thanks.

Bill
