Wiring harness advice

After a small engine compartment fire at the Mopar Nationals in the early 2000s I needed to buy a new engine compartment harness. I was at the Nationals so I knew that finding one would not be an issue. I purchased one and proceeded to install it in the hotel parking lot. While installing it I had several wires with "crimped" terminal ends pull right out of the connectors. We had to remove and re-crimp them all. Watch what you buy.
