Installing an American Autowire Classic update wiring harness

What does the AAW kit do about the bulkhead connector? Is there a plate included to patch the hole?

The AAW kit has its own version of the bulkhead connector that attaches to the back of the fuse block. The bracket it uses requires a couple of holes to be drilled to mount it, but all the wires pass through the same area. The kit comes with an adhesive template for the firewall to drill the new holes.

Engine bay side (pardon my dust)
