Painless Wiring 60509 - 1998-2002 GM LS1 Harness Extra Length

This harness is designed for the 1998-2002 LS1 mechanical throttle body engines using a 1999+ LS1 / LS6 ECM with a 4L60E/4L65E automatic or T56 manual transmission. These engines were found in 1998-2002 Camaro/Firebird. This harness will also work on 1997-2004 Throttle By Wire (TBW) LS1/LS6 engines which has been changed to mechanical throttle body or any 1999-2006 (4.8, 5.3, & 6.2) Vortec truck engine which has been changed to a factory of aftermarket LS1 intake manifold, mechanical throttle body, and injectors. Harnesses do not include any emissions related connections but are available separate. Included with this harness is an 8 circuit modular fuse block and GM color coded wires with labels for easy installation.

This extended length harness allows eight feet from the back of the intake manifold to where the fuseblock and ECM mount. Perfect for those that plan to mount these components under the seat or in the center console.
