The LS6 wire harness or LS6 wiring is designed to run in almost any environment imaginable. The way we designed the LS6 wiring / LS6 harness places the ECM in the passenger side fender, or inside the car, length permitting. A common transmission is the T56, which is what the harness above is designed for — we can also create a 4L60E option in any of our LS engine fuel management wire harnesses.
We have programs available that will allow you to successfully run a no-emissions engine, with whatever transmission you desire: 700R4, T56, 4L60E, 4L65E, 4L80E, NV4500.
