This extension harness from Aeroflow Performance is used to extend the factory TPS wiring on your Ford Falcon BA/BF models only. This is great for when the user is doing an intake manifold conversion with a forward-facing throttle body with an aftermarket plenum. Usually, the wiring comes up short with this conversion and this harness makes it that much easier. We also recommend purchasing the DBW throttle body extension harness (sold separately AF49-1546) to match.
