Take the wiring headaches out of your LS swap and get your build moving.
When you’re putting together a drive-by-cable LS swap with a 4L60E, the last thing you need is a wiring mess slowing the whole project down. The HPI 1997–2006 LS1 Standalone Wiring Harness Drive-By-Cable for 4L60E is built to simplify the install with a standalone setup designed for 1997–2006 LS1 engines and 4.8L / 5.3L / 6.0L Vortec applications using a 3-wire MAF and 1-wire alternator.
BUILT FOR DBC LS SWAPS
This harness is listed specifically for 1997–2006 drive-by-cable LS1 engines and is sold as a standalone solution for 4L60E-equipped applications. The live page title also targets 4.8, 5.3, and 6.0 Vortec search terms, making it a fit for builders searching within that swap family as well.
CLEANER INSTALL. LESS GUESSWORK.
HPI describes this harness as including the needed dash connections, including speedometer, tachometer, park neutral, TCC, malfunction indicator, and a DLC port. That helps streamline the swap and reduces the amount of custom wiring needed to finish the build cleanly.
BUILT LIKE A REAL SWAP HARNESS
The live page states that all harnesses are built with OEM quality and better, use GM color codes, include a high-quality sliding grommet, reinforced ring terminals, factory CPA locks, and 1200-degree fiberglass braid on heat-exposed circuits. The harness is also listed as receiving a quality check before shipment and being 100% handmade in the U.S.A.
READY FOR BIGGER INJECTOR SETUPS
The page states this harness includes EV1 injector connectors and offers free adapters to convert to EV6 or Delphi Multi 4.8 / 5.3 / 6.0 injector connectors if needed. It also lists upgraded wire for running large injectors and upgraded 60-amp relays, which makes it a better fit for performance-minded builds.
