So I recent bought a 2009 Sierra with the 5.3 LC9, the only issue wrong with it is that it’s going to need a complete engine harness as rats have torn through it, will a harness from another Sierra fit? Or does it have to be specific, I found one on eBay, only difference that it was meant for a 5.3 LMG, mine has the LC9, both trucks are 4x4

If both trucks don't have VVT, then they should be the same harness.

 

The main difference between those two engines is usually just iron block to aluminum block and if they ran flex fuel.
