Gen 2 LT Optispark Extension Harness - Long

Overview

The PSI Gen 2 LT Optispark Extension Harness (Long) extends the factory Optispark distributor connector on 1992-1997 LT1/LT4 Gen II engines, giving you extra reach when the distributor needs to sit farther from the factory harness routing point — common in OBS truck and street rod LT swaps where the engine is set back or the harness is routed differently than in the donor vehicle.

• Plug-and-play factory-style Optispark connector on both ends
• Long length version for extended routing situations
• GM Delphi-style connectors and TXL high-temperature wire to GM spec
• Pairs with our HAR-G2 Gen II LT1/LT4 standalone harness

Compatibility: 1992-1997 LT1/LT4 Gen II Optispark distributor applications.
