Cruise control cutting out. Need help finding correct brake light switch

[Danpatters583]

So I read on here some more troubleshooting tips for cruise control. And I determined that my brake light switch is just a bit more worn out than it needs. To make the cruise control work consistently that is. 

 

My question is how many brake light switches are there on these cars? On line they show two. One is called a cruise control release switch? Says it fits 88-90. Mine is a 1990. 

 

Which one do I go with? 

 

Any help would be much appreciated!

To the best of my knowledge and consulting the wiring diagram, there are three "switches" connected to the brake pedal. Two are electrical and one is the mechanical vacuum dump for the cruise control. The cruise control has a normally closed electrical switch and the brake lights has a normally open electrical switch.
