[T3] Tach signal

[shalom@ucla.edu]

<x-flowed>Again, thanks for all your advise on the starter...my starter is 
working.  Turns out that replacing some old fuses and replacing the 
grounding strap from the battery to the frame reduced the voltage drop 
to the solenoid.  I'm actually currently switching over to a ford 
solenoid relay as an upgrade.  Just need to get some lower gauge wire.

I have a question about getting an RPM signal for a tach.  I have an FI 
distributor so I have a connection with pins (21,12,22) that goes to 
the computer.  Do I use either pin 12 and (22 or 21) to get the  RPM 
signal?  Or do I get the RPM signal some other way (maybe like an 
engine that is not FI)?  Does the distributor shaft turn 1 revolution 
per 2 revolution of the crank shaft?

Thanks,
Shalom
