MS2E HELP!

Hey guys, I went to hook up my MS2E I bought from REV for my MSM.
I got everything hooked up, but the problem I'm having with my AEM UEGO.
I had it hooked up the in car along with my boost gauge first, then I ran the blue wire to the MS2E.
So Power and Ground came from Radio.
Went Blue wire to the serial wire Rev supplied, in the MS2E, and it wouldn't read inside TS.
Next I reread the instructions, and I wired the Wideband to the MS2E (Black/Yellow for Ground, and White/Red for power) and my wideband wouldn't come on.
I checked it with my tester and there is power on the B/Y and W/R!!!
I went ahead and grounded the wideband to the B/G and the wideband came on. My laptop is currently charging right now, so I haven't had a chance to see if it works with TS yet.
Any suggestions??

I'm confused just reading that...
I have the same MS2E as you but don't use the AEM UEGO so assuming the DB37 pinouts are the same (I use the AEM Inline UEGO);
1. The AEM UEGO says to source 12V switched @ 10amp. So you shouldn't get your power from the MS2E (only 5a internal fuse). So source your 12V elsewhere. --- Lighter connection maybe
2. MS2E DB37 Pin 2 (BLACK/YELLOW) --- BLACK out of the AEM UEGO
3. The MS2E DB37 Pin 4 (Yellow) --- WHITE from the AEM UEGO
4. The AEM UEGO BLUE goes unconnected
Don't think I forgot anything.
Don't you have a pinout from Rev for the DB37?

Hey,
REV told me to connect the wideband BLUE to the serial connection.
I found the problem, it was in the connector the B/Y was either not soldered, or bad solder joint. A youtube video, and trip to home depot to buy a soldering gun fixed that. Wideband is now powering up, but still isn't displaying in the TS.
I did get base ignition setup, but on the timing display is fluctuating.
I did a quick log to show, is the timing normal??

I think I have the solution. Pin number 5 here needs a ground. I'm assuming a chassis ground.
So I think the MS is expecting ground from pin 5?
I'm going to give it a go tomorrow in the morning. I've put my car back to stock to drive it home.
Also can someone take a look at my log for the ignition advance? It continual bounces around (and I'm assume that's right, since the RPM's are jumping, ignition should advances to correlate with the RPM's).
