Why I Believe a Stand Alone Wiring Harness is Necessary

As a car enthusiast and experienced mechanic, I have come across numerous situations where a stand alone wiring harness was necessary for a proper and efficient engine swap or modification. Here are my top reasons why I believe a 5.3 stand alone wiring harness is crucial in certain situations.
