Tunerstudio not reading Innovate PSB-1

Hey guys,
Here's the situation - for some reason, my Innovate PSB-1 wideband is not communicating properly with my MS2 PNP. Here's how i have things wired up now:
Red - 12V to add a circuit
Black - Grounded to back of engine
Yellow - Wired to options port 21 on MS2
White - Wired to dimmer source
Purple - N/A
The way things are wired up now, the PSB-1 is working fine and reading AFR's but in tunerstudio it's showing 0V - 7.3AFR. Settings in Megasquirt are:

I've done the following to try to get MS/tunerstudio to read properly:
-Switching wideband signal to other Innovate (LC-1, MTX etc)
-Checked yellow wire to ensure voltage is being sent (current reading is 12V) - Should this be 5V and not 12V?? Maybe that's my issue?
-Grounded black wire to options port 5 and 22 (when doing so wideband does not turn on)
-Ensured pre-cat stock 02 plug is taped off
-Cut post cat 02 sensor plug and taped off all wire ends
I'm stumped.. what am i missing guys?
Here's a link to the PSB-1 manual. Page 4 covers wiring and Pages 12/13 showing analog output (0V = 7.35AFR & 5V = 22.39AFR)
