Rewire your project truck or car that has a Gen3 4.8L / 5.3L / 6.0L engine and 4L60E transmission with one Painless harness, the 60617. Engine codes supported are LR4, LM7, LM4, LQ4 and LQ9. All required chassis to fuel injection harness integration has already been done for you. Four easy steps to upgrading your vehicles wiring:

• Mount the integrated fuse block under the dash.
• Mount the PCM under or behind the passenger seat, under the dash, in the engine compartment, behind the headlight buckets or in the fender.
• Route and connect the wires according to the fully illustrated installation manual.
• Drive the vehicle and enjoy all of the creature comforts expected from a brand new vehicle.
  
  Great features only found in the 60617:
• 26 circuit/ 7 relay fuse block.
• Fitment = 1999 - 2006 Gen III mechanical throttle body fuel injection with 4L60E automatic transmission harness and universal chassis harness (GM color coded) integrated into a single fuse block.
• Includes connections for factory style LS1 Camaro cruise control module.
• Mounts ECM in engine compartment, under the dash or under the passenger/driver seats.
• One fuseblock with no external fuses or relays to mount.
• No extra relays to purchase for standard installation.
• If fuse block expansion is needed, relay kits that clip to the side of the fuse block are available (add up to 5 expansion relays).
