engine swapped issue
 

I blew my old motor in my 01 s60 2.4t. I then bought a 2.4t motor out of a 01 v70 2.4t wagon. they are the same motor but mechanic told me that my old engine harness wont was not directly wiring up with the v70 motor. my question is, I I buy a v70 engine harness will everything wire up correctly
