'74 Swinger brake lights issues!!!!!

Hello, I've just bought my first muscle car (always wanted one) a '74 Dart Swinger. I'v been working on little things on the car untill I have the funds to do other fun work. (My knowledge is not too professional with my car)

My first problem is with the brake light solonoid wires. I put in a new solonoid and for some reason I got spaked on the metal solonoid detainer/thing =P I plan on replacing the wiring harness but for now I want to fix this. I do no get sparks on the wired any more so the brake lights dont flash. What do i need to do? Its not the fuses because I replaced them and are working fine. Did I burn the wires nd if so how do I fix this??

!!!ALSO!!!
My left brake light will not flash/blink when I put the turn singal, the right side will though, whats the cause of that? wires? How can i fix this?


THANK YOUUUU!!!
