There's a YouTube video showing a supposedly successful MT-82 swap in an '06 GT. Apparently a Dakota Digital SGI-100BT speedo/tach interface was the trick to getting the stock speedometer to function but there is zero info on how it was wired in. As far as I can see, Dakota makes no claim that the box can convert one signal type to another. It's possible you could get it working by feeding a wheel speed sensor signal into the Dakota Digital unit if the MT82 OSS sensor ends up being a no-go. I'm not sure if splitting that signal could cause ABS/TC issues though.
