Hey, we got everything and wired up but there is some buzzing feedback coming from the dash.. any idea what that could be? Mechanic think its a faulty speedometer/cruise cable.. I thought the tachometer was supposed to filter that buzzing and jumping
WHAT is jumping? The tach or the speedometer? Is the circuit board tight?
If the speedo is jumping around, the cable may be messed up. It's called "whipping". That could also be the source of your buzzing. Does the buzz happen all the time or only when you're moving? If it's the speedo cable, obviously you will need a new cable.
On the tach, if it's jumping around, it could be a filter thing, or could be the orange clip thing on the back. You put the orange clip in the 6 or 8 slot, depending on which engine you have, a V6 or V8. It wasn't until 86 or 87 they figured out that they should just solder a jumper piece across the tabs because the clips always became loose or missing over the years. If the clip is loose, you could be making contact and then not, as the dash vibrates so does the clip. Thus, the tach jumps around.
I'm not there. So I'm only saying it's some possible things to consider when troubleshooting.

Try to go with the year of the car as you need to match the sender to the car gauge.
I think you’re referring to the capacitor / condenser that was factory installed on the Monte Carlo‘s with tachometers. To my knowledge the G body Cutlass tachometer never required this part. You can direct wire the tach from the distributor lead on a cutlass.
