Instrument panel wire reattachment position?

[Whaledriver]

I made the mistake of not photographing the back of my dash instrument panel when removing it, now I can't remember which post I am supposed to attach two remaining  wires that go to the tach. One is a green one already attached, comes from the black vinyl harness and the other that  looks black that comes from the interior and not shown in the picture (could be power source from tack?) I am sure that the already attached brown wire goes to the power symbol post. My manual shows only a normally installed clock wire in that position.

Tach wire from main harness is black and goes to the center terminal.

The green wire goes to the "+" on the tach.

The black wire (from the coil) goes to the "1" (center) on the tach.

Brown to the ground terminal.

To both of you, Thanks for the clarification. I'll remember to take photos from now on during disassembly.  Gregg
