Is that not the same as going to the cab?
No its not the same. If that is all the grounding that the cab has that is classified as a bad ground. It might work but its not right.

Stock, the cab had 2 grounds to the back of the engine from the firewall, and 1 to frame.

You mentioned that you ran a ground from the booster bracket to the valve cover? Run it to the block or head. No paint under the connections, use a star washer for good contact.

This might not solve your problem but should be addressed anyhow.
