Vfaq under electrical. All the pinouts are there. Should be pin 21.

But, pin 21 is only a 5 volt signal from the CAS, so it may not be enough to drive the tach. You should probably try pin #109 first, which is the one the dash tach works from.

look in the how-to section. There's a nice color coded diagram I put together.
