Hello, Dave here, contributing to RepairPal and providing expert advice since 2010.
I think you are on the right track. In my experience, the brake light switch needs to be replaced but also the wiring connector. Using tape for the wires is not sufficient to resolve the concern. This is definitely just a guess but it's an educated one because this is not uncommon for this vehicle.
Replacing a wiring connector is not something simple for the novice mechanic. It requires skill to make sure that you were doing it right and not causing a fire hazard. I know you don't want to spend money on a mechanic near you, but you might need to reach out for some advice at the very least.
