Auto Console wiring plug

Ok guys..
I'm converting colomn shift dart v8 auto to floor shift....
I have bought the repro harness to do the job...
Can anyone tell me where it plugs in??
I'm sure somewhere near the fuse box as it has a separate earth lead which would screw to the body....
I can't seen to locate a plug???
Thanks in advance

Hey John Dodge.

Pretty sure that plug goes to the neutral safety switch which is attached to the shift lever mounting bracket. Also controls the backup lights. ground wire goes to floor sheetmetal.
