Engine RPM feed

Post by xmas6 » Sat Mar 31, 2012 5:11 am

Hi All - I need to find a reliable source for the engine speed to install my S/H Prins system.
The car is a BMW 520i with a twin vanos M54 engine.
I was going to use one of the cam sensors or the crank sensor but i`ve been told these are notoriously `flakey` om BMs.
Next thought was to use the rev counter signal.
Can anyone advise and help me identify which signaland wire to use?
Cheers Neil
