I'm swapping a Toyota W58 in my 1995 LS400 but can't figure out how I'm going to get the speedometer working.

I've seen several posts all over the internet but none of them ever really seem to give me answers.
What's the easiest way to retain speedo and odometer function with the new transmission?
I've seen plenty of 2 pin electric to 3 pin mechanical converters but can I convert it the other way around?
Or would splicing the signal from one of the ABS sensors be easier?
