Can a FAST activate a shift light ?...

[toofastforyou]

I just ordered an Auto Meter shift light for my car along with a "Rpm Activated Module" into which you plug the rpm "pills" to activate the shift light. My question is: Is it true that the shift light can be activated by the FAST XFI ?... If yes, I'll keep the light, but return the unneeded module and pills...
Also, if "yes" to my first question, then how do I enable the FAST to turn the shift light on?

Thanks,

Claude.

P.S: Someone replied to me on the "TB.com" site saying that all I need to do is to "Get a wire into pin "B1" and wire it to one side of your shift light,and wire the other side to key on power.
Go into your XFI and set the AUX output 1 to the RPM you wish it to light at."....That's correct? Also, I'm not sure if pin "B1" is in the ALDL connector under the dash, or pin "B1" in the XFI harness or the XFI unit itself?? I'd need a pin to plug into the empty slot in the harness connector @ the b1 pin of the xfi...
