Auto Console wiring plug

Thank you Jim....and for everyone's input..
Ok I need to be a bit clearer....
I bought a repro floor shift harness with console tach wiring.....
I'm converting my 68 dart to floor shift....from a colomn shift with intention of finding and fitting a orig console tach..
So
Yes the nss is the single pin switch in the transmission....
The reverse lite switch is on the bottom of the steering column and its wired up as original
This car is a one owner 70k mile survivor so no wiring hacks here its completely standard in that dept....
So I have taken put both kick panels there are no existing plug for this floor shift loom to plug into.....
I have scoured under the dash...no plug...
It would seem by laying the harness out on the tunnel etc it should be routed left or right as it has the length to do that....
I'm still figuring towards the left as it has to power up the light circuit, the tach circuit and and the reverse lite circuit ...so it has to draw current ...
Any further clues guys??
I'm getting the impression the colomn shift dash harness is different to the floor shift harness ....so I may have to splice into the original day harness......???
