LT4 Wire Harness

The harness was catered to have no emissions, 2 heated O2 sensors, T56 trans, pigtail for a digital Speedo and a pigtail for the Tach. Speed Scene Wiring pushes the custom harness envelope by providing a quality 5-wire manufactured harness.

This application was crafted to be placed on a 1965 Corvette with late model suspension and a T56 trans. The wheels of choice for this installer are the new C5 Corvette rims.

The beauty of this is, it's easy for the customer to install his harness when he receives it. Every harness is labeled in clear English — no ad-libs or acronyms. Just plain English.

All harnesses can come equipped with cooling fans for an additional price.
