Just did a head swap on my z6. Replaced the stock cam valves and springs with Bryan crower stage 3 cam,valves, and springs. also had to put a y8 intake manifold on. Aswell as a ac and power steering delete. Having problems with my break lights flickering on and off. My running lights and dash lights seem to turn on when I engage the brake pedal too. Checked all fuses and the brake pedal light switch all good there . In the process of going through wiring, would there be a headlight/brake light harness or ground i am missing to check? That could be crimped or disconnected. Just confused here some advice would be highly appreciated Thanks
