Because we are swapping in an ’03 GM 6.0L V-8 (a pretty common engine swap due to its good power and simple installation), we opted to source a harness for the swap. Many companies offer harnesses for these GM Gen III and IV LS series engines, but we chose Pacific Fabrication (Pac Fab) because those guys not only do a lot of LS engine swaps at their shop but they are also four-wheelers, so they understand the performance needed off-road.
