NOS 122 Wiring harness, with mystery pink wire?

[A Urban]

Hi all,
So I have a 122 I'm replacing the harness on. Its an NOS harness I had picked up for a 123 I used to have, & never installed. I've got the wiring diagrams, but pink wire isnt shown on it.
I labeled one end (small lug) on the old harness, which came off the bottom mounting bolt on the regulator (ground). My dumb @ss forgot to label the other end (large lug).
Is it supposed to go on the large terminal on the underdash solenoid, opposite the BAT terminal? or..??

Thanx

Pink wire is a ground for the voltage regulator. It mounts to the right front dash tower bolt.
