The 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. The above harness application was  hand crafted and placed on a 1965 Corvette with late model suspension and a T56 trans.

The beauty of this is, we make it easy for the customer to install his / her harness once received. Every harness is labeled in clear English, no ad-lib’s or acronyms. Just plain English. All harnesses can come equipped with cooling fan relay triggers tailed out. No relays. Price quoted below for any transmission you require.


Just as important at the wiring, in fact some think it’s more important. We can custom blueprint the wire harness to the operating system of your install. This assures the entire package will actually work in unison. We also understand that you may have a file inside the ECM right now, the program could also be corrupt. its always a great idea to install new code – when its available.
