Since my first FB is now a parts car, i'm wanting to take the shift buzzer from it and wire it to another car, no real point, i just miss hearing that buzz at redline. Where is this unit located? What activates it to sound, is it triggered at a certain voltage, or is there something that sends a signal to it at a certain RPM? Basically, what would i need for it to work with another car?

Another way i could see doing this is through the Check Engine Light (CEL), my ECU has capability of throwing a CEL for a shift light at a certain RPM, what about wiring the unit to the CEL bulb, would that work?

 

it works off the tach and attached to the back side of it. at least on my 3 it is.

 

I saw that it was on the SA as well (checked my Haynes), but on the back of my FB's cluster (S3), there appears to be no speaker for it, just the circuitry on the back of the tach. I'm looking for where the speaker is located for it.

I've read since posting this that there's a circuitry panel for it and an adjustable screw to set when it's alarmed, so that clears up what activates the sound, now i'm curious where the sound comes from.

 

I'm pretty sure i traced it to being this, there's no way i'm going to be able to use this easily.

 

I actually want to put a bunch of foam around it so I don't hear it...I assume you're talking about the little goldish box on the top of the cluster?

Can anyone add to this....bringing up some old history here...
