zongshen electrical

My 06 zongshen dual sport had a cracked brake light and front signal light. I ordered some new ones and tried to replace the lights myself. I unplugged the wires for the brakes and had to plug them back in because I need wire transitioning to finish the job. I reconnected my old brake light and now it's always on, as if the brakes are being applied all the time. Also, after swapping my turn signal lights, both sides now come on instead of either one that I activate. If I click my signal to the left, all four lights stay steadily on(front and back, right and left), and my brake light is constantly on as well. Should I have unplugged the battery before tinkering with the light wires? Can anyone help with this?

Thanks in advance

My guess is that the new turn signal lights are LEDs and the old ones are not. If so, you will need a new relay. Do a search for motorcycle LED relay and you will see some results. Most are plug and play. I'm also guessing that you changed the signals first. If so, the above is what is causing the tail light to stay on. Changing the relay will fix this also.
