Tail and brake light issues

My blinkers work unless I put on brakes and then they stop. The brake lights only left one works and I have no taillight when headlights on. I had a guy install the power brake and had read there was A Switch of some kind on master cylinder.
There is a switch on brake pedal inside truck also.

Went back and found old picture and looks like my Dad removed the one on mastercylinder. Should have wires on it right ?

No wires on the master cylinder switch should be correct since your switch is on the pedal. The pedal switch should be using the same wires that were on the master originally.

Could be the brake or even turn signal switch, and make sure it's not just the bulbs, but the similar issue I dealt with was solved after I cleaned up the screws and threads that attach the tailight assemblies to the bed (behind the lenses) That's how they ground to the body. You'll sometimes get weird behavior like that if there's a marginal ground. You may have to use something like steel wool wrapped around something small to really get the threads clean.
