Where do I connect the Console Harness ground wire on my 69 Z28?

So I just finished rebuilding my center console, and have installed a new console wiring harness. A little less than half way up the run to the ash tray courtesy light there is a black ground wire. Where is that secured to the body? Does anyone have a decent picture of it?

1969 Z28, 4-speed console with gauges.

Thanks!
