Jaguar current sensing technical details?

I don't know if the Jags use high-side, or low-side, or some other switching method. Does anyone know, definitively, what switching method the Jags use? I've heard many different claims.

Kevin Sevick has posted information about the Tan and Black Jag switching.

I could not edit my earlier post in this thread to reflect this new information, so I am attaching an updated image here.

Also, there's an error in the Tan Jag image. The blue line should be shown going through the Q10,11,&12 FETs, not their Zener diodes.

First, here's the datasheet I'm working from. The latest and greatest from TI itself:INA193 datasheet

I see the note about the swing range of the output, but there's additional notes just above that and on page 8 and 9 that declare the output bottoms out at 300mV typ. Perhaps the 300mV thing isn't the dominant issue and it really will swing down to 3mV with increased error. It's kinda hard to decide, which all the more inclines me to just empirically test the thing.
