This is probably a stupid question, but I don't know too much about the heart of the Volvo electronics... I just bought a 1999 S70 that does not have traction control... but I own an S70 that I am using for a parts car and it has traction control.

Can I just switch the ABS Module out and the on/off switch on the dash and make my "new" S70 have traction control or is it in the cars ECU? I would assume that all the wiring is already in the non traction control car...
