i found a complete kit(diff, wiring and controle module) for a 957 tts that had the rear locking diff. I just bought an 09 S that doesnt have it. is it possible to install it and have it programmed into the car?

You better research differential ratios between turbo and S. If it's like the 955, there are 3 different available depending on base, S, turbo and manual vs auto trans.

Could this be found out with the VIN?

Possibly, but when I bought a front replacement I just looked up the part # for my year and model from an online vendor.

@bbqlord I will make mention there is apparently a good deal of difficulty splicimg in the necessary harness connections. I looked into this a bit as well.

thanks ill look into this. the seller doesn not have the truck anymore so i is the part number written somewhere on the part so i can verify?
so i understand its "doable" with the right amount of money and time to figure it out lol.
