I was planning on using this cable to connect into the tach signal for my g2xtreme data logger. Basically connect it to the OBDII port, run the cable back to the logger, clip the other connector end off, and use the wire from pin 9 to the RPM sensor wire coming out of the logger and solder them together. There is also a power and ground available from in the OBD cable. Can I use these? The wires are a pretty small gauge, so will draw from the data logger be too large? Otherwise I can easily draw power from the 12v socket in the center console. Thx for opinions

+1 on powering from the center console or cig lighter. IIRC there is a max current draw a device could/should take from the OBD port, and it was less than the G2X would need (at least on my 996GT3).
I actually use the cig lighter, got one of those plugs from Radio Shack with a switch and LED on it so it is easy to turn on/off and see the power status. Also, you can get blank OBD2 plug kits from Peake Research if you want to make a custom cable.

Looks like I'll use the Cig Lighter as planned

I have a stack setup in my 996GT3 RS sequential but wouldn't mind taking the street car on track once in a while to work on lines etc instead of the expensive RS

I use the cigarette lighter option to power the DL-1, although I later hard wired it. I did not use power through the OBDII

Yes you can grab tach and power. There is both always on 12v and switched 12v, I would recommend the switched 12v. This is capable of 5 amps before blowing the fuse, much the same as the cigarette lighter. Make sure you use chassis ground and not sensor ground.
Most cars have a CAN bus that you can splice into. All your engine and speeds come through this CAN bus, but only more expensive loggers like the Stack and Motec have this capability.
