Aeroflow Standalone Wiring Harness T56 Manual Trans suits GM LS1 AF49-1512
GM LS1 with T56 Manual Transmission Wiring Harness
Standalone Plug and Play Complete Engine Harness
Aeroflow Performance wiring harness is designed to be a complete plug and play harness for EFI GM LS1/LS6 series engines. It is a complete standalone replacement wiring harness that suits GM LS1 engines (1997 to 2002) with drive by cable throttle body and T56 manual transmissions or non-electronic controlled automatic transmissions. Perfect for retrofitting into older muscle cars and street rods or newer non-emissions-controlled vehicles with a four-wire hook-up (switched power, constant power and ground connections). The harness features a sliding grommet seal for a leak proof installation and 1.2 to 1.5 meters (3.9 to 4.9 feet) of length from the rear of the cylinder head to the PCM mounting position under the vehicle dashboard. The harness is constructed with GM Delphi connectors and terminals and high temperature wires. It includes all wiring that is required by the Powertrain Control Module (PCM) to run and control the fuel injection system.
