89’ pink/black and purple wire

Me thinks that spot to the right side of the BLS is the vacuum disconnect for the Cruise Control. Step on the brake pedal and it opens the vacuum valve to relieve vacuum to the vacuum motor to disengage the CC. The brake light switch has 2 connections. One for the brake lights, one for the trans relay. If you have deleted the trans wiring then only one connector is needed for the brake light switch. I hope this helps.

Gotcha top one
Weird thing middle one for stop light and at trans tc lock up has wide prongs for brake and narrow for AT tc but plugs are both wide?
I guess it doesn’t matter since the guy that did my transmission put in the B&M torque converter switch. strange that the purple and pink wires have a wide connector and the prongs are narrow
