4 speed console wiring question?

Here's what I have now. Unfortunately I didn't take pics when adding the lighter & harness. We used a lighter receptacle that has provisions for a ground wire attachment similar to the one pictured below. It's wired to only work when the ignition is in the ON position....

I don't think the floor shift consoles are grounded & require a separate ground for the lighter to work. Hope that makes sense....

This little plug-in gadget is handy to check battery/charging conditions on the car :)
