Signal-Brake lite issue

Hi after reading you replies i will give a bit more information. Keeping in mind everything worked finetill i changed the carpets on a console shift car with factory air (so extra work tighter fit)
When you pull the head light switch both front & rear parking lights & the head lights work.The 4 way flashers work from the switch ,neighter of the signal lights work from the arm,when you push the brake pedal down both brake light work but at the sake time both front signal lights come on (high side of the bulbs) and stay on till the brake pedal is released.

If everything i am reading is correct it sounds like a ground problem.
Where would i start running new grounds to first?
