So reading lt1swap.com...notation for '99-'02 wiring.

"PCM can be programmed to accept a SINGLE WIRE park/neutral signal on this PIN, if no trans mounted range sensor is present"

pin is Blue 34...

Can this be done w/ EFI Live? Found some references online, but some say it can't be done unless you have HP Tuners or Tuner CATS?

Working on another harness for someone, and they're going to be running a TH400.
