Questions about pulling timing with the Traction Control tables

In lt1edit the traction control tables only go up to 6400. If i do 5^ retard at 6400, will it just carry the 5^ for everything above that, or will it default to max advance?

Also, has anyone actually done a setup using the traction control input. I found one post with someone describing it, and one post with someone saying they couldn't get the right signal to the pcm. If so, do you apply ground or 12v to the input line?

I answered my own questions. Ground the input for traction control on the pcm, then anything above 6400 it will use the last cell specified.
