A-trac install on 2013 sr5

I got a question has anyone dealt with the A-trac system before? I was wondering what it would take to install on a 13 sr5. I know the break booster is different. I'm sure wiring is different.

 

Probably needs a new skid control ECU and about a million $ worth of wiring. In any event, not really worth it. Just do the yellow wire modification and call it a day. Yellow wire modification allows the TRAC to work when in 4L, which is almost as good as aTRAC. Other things you could do that would also be improvements, without swapping out a bunch of stuff that you shouldn't mess with; mechanical LSD and/or LOCKER.
