Thread: What is this thing under my bonnet?

Just purchased a lovely early 84 V8 RR and have been giving it a full service and tidy up under the bonnet, but i'm confused to what this "after market" looking item is.
It has wiring going to it and then a cable (looks like throttle type) going under neath the carbs to a lever.
It doesn't seem to do anything when reving the car the cable just bends back
Any ideas, and if it does bugger all can i just remove it?

Poor connections, broken wires........

I suppose the control unit or the vacuum gadget could be faulty, but both have been faultless in mine. My most common issue has been broken wires, followed by the accelerator cable breaking, and a bad connection at a plug.

The sensor is a pickup coil on a bracket close to several magnets wired to the propeller shaft, in my case the front prop shaft, just in front of the transfer case. This is a relatively vulnerable spot, but seemed simpler than accessing the rear shaft behind the handbrake drum, which would have needed a long bracket. Another possibility is a blocked or missing vacuum line (teed into the line to the brake booster).
