Help Needed Finding Tach Wire (rev Counter)

[south west motorsport]

Hello, im currently installing a new alarm system to my car and i need to locate the pick up point for the RPM, usually this would be wired onto the minus - side of the coil but i think the scooby is slightly different running coil packs. I have been searching high and low for this information for the last day or so, as a last resort i could maybe hack into the wire behind the dash board that goes to the RPM dial, so a wire colour of that would be useful.

In a nut shell - i need to know where there scooby gets its rpm reading from on the engine.

Thanks

Ben
