On the subject of proper ground, I discovered that even with the gauges bolted to the steel dash plate I would see the gauges and dash lights work with random intermittence. I ended up running a dedicated ground from one gauge cluster to the other, then to the firewall; that finally chased off the gremlins and got everything working at the same time.
