07 SS ECM problems
 

Hey everybody new to this site and Cobalts, recently bought a 07 ss/sc with a blown computer for a great deal but the owner told me that it had an issue with reverse. He said that it burns up the computer every time it is put in reverse and would need a wiring harness replaced which he gave to me out of another cobalt ss. Just wondering if anybody on here have encountered this issue and could lead me in the right direction
