Wire for Brake Distribution block - 73 Duster

[moparspares]

My cable for brake distribution block is missing. What is the routing of this cable, I assume it ends up at the brake light switch and what does this thing actually do.

The warning switch is a two-way piston, normally centered which is "off." When a leak or other problem develops and cause lower pressure in half the hydraulics, the pressure forced the piston to one side, grounding the switch. This activates the brake warning lamp on the
dash

Run over to MyMopar. You can download a 73 service manual (two volumes) absolutely free. That manual, and several others "over there" got there because of the guys on this site
