Both Tachometers are working. I hooked them up temporarily to the ramp truck to see if they would work. Scared me the first time. Neither one worked. I then looked and the 12 volt wire was not hooked up to the fuse panel!!!

They both work now. But they both read differently. So tomorrow if I have time I will see about adjusting them if I can.
The guy I ordered the board from said it was adjusted to a v-8 already though.
It looked to be right around 4-5 1000 in neutral.
The brothers was more like 6-7 1000.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
