2000 E46 318i - Revcounter wiring

Hi, I suspect the revcounter on the E46 is digital, but it still needs some input from the engine to the computer to operate? Where does it get the signal from, the crank sensor / cam sensor? No matter how many times I Googled it, I can't seem to find any info on this..... If anyone can assist, I would really appreciate it.
