I also use a TWOG and a Razor IMU like you. In my case it works. You have to connect the accel and gyro channels according to you r configuration file. Needles to say, you have to connect the 3.3V and GND rail. You might have to remove the highpasses from your IMU, if you have the old version (see the schematic). The most important thing is, that you have to bridge the resistors in line of the Voltage deviders on you twog. And you have to remove the resistors to GND (also see schematic of the twog).
As I wrote some times before I for myself am still using the SW in my pretty old branch, but it is working. For more information see .

Good Luck

I have a tiny 2.11 and a Razor IMU(still not working). But I have wired the outputs from accelerometers(Ax, Ay, Az) and gyros(Gx, Gy, Gz) to ADCS in the tiny(in my case, ADC0…ADC5). Then I have wired GND an 3.3V to the tiny too. Finally, in the flight plan I have defined which ADC is everyone in the firmware section (subsystem: imu)-you can see an example in conf/example_twog_analogimu.

Hope this helps.
