I don't have a truck running let alone the cummins in yet, so don't know if they work. Everything looks good, circuit board, inside the tach/gauges, so I don't know why they wouldn't work. I had one tach that you could see some spots where it got hot, all of these look brand new.

The diesel tachs came out of Asplundh tree trucks, other than being rusty used and abused, think they still ran.

The diesel tach posted above has a vacuum gauge in it, I think it came with a single air gauge, but the other diesel cluster has dual air needles, thought that was kinda cool.
