FSD extension harness

[dilemma]

Does the Kennedy extension harness connect to the existing PMD harness or will I need to remove the intake manifold and replace the existing harness with the extension harness. The reason I ask is because the red wire that connects to the rear of the injector pump is not accessible with manifold in place.
Thanks

Think of it as an extension cord, It comes with a male and female connector.
