I installed subs in a friends car which was the Ford fusion everything worked great but as soon as I buttoned it all up and he went to leave his car wouldn't shift out of park and it also had no brake lights we checked all fuses in engine bay and replaced brake switch but same issue still persists it's not the cable bushing because with the shift lock release we can get it to drive just fine. All help is appreciated thank you.
