brown “L” (regulator), goes to (junction) to volts indicator light (in the instrument panel)
[the brown wire is called the “field” wire]

.

OTHER NOTES:

The volts indicator light is part of the charging system, if it burns out, the alternator may not charge the battery!

[SEE Volts light]

This might be of some use:

FieldFix alternator volts light fix
FieldFix™ ALTERNATOR PLUG-IN by Casper’s Electronics #6961
The FieldFix™ Alternator Plug-In by Casper’s Electronics “plug and play” wire harness is designed to assure uninterrupted charging system function on your Turbo Buick or Turbo Trans Am.
The FieldFix™ forces field current to the alternator whenever the ignition switch is on, and eliminates the possibility of not charging the battery due to faulty wires, burned-out ALT (volts) lamp, aging dash cluster flex-board connections, dash wiring problems, etc.
It accomplishes this by providing current to the field winding or the alternator whenever the key switch is turned on.
We highly recommend this item because if the bulb for the (volts) alternator light in the dash burns out, the charging system will not function! By having this installed in your car, the charging system will still function properly.
FieldFix™ comes with easy-to-follow directions. It simply plugs in and no wires are cut. This harness provides the alternator with its field current, acts as a “safety net” for system charging and assured full charging capability to the car’s battery.
