AUTOKAY Injector Adapters 8-Pack — USCAR/EV6 to Delphi Mini for LS2 LS3 LS7, Plug-and-Play

If you're swapping injectors or upgrading an LS-series engine in a 1999-and-newer GM truck, these AUTOKAY adapters provide a clean, vehicle-specific electrical connection without cutting factory wiring. Each kit contains eight individual adapters designed to mate the factory Delphi mini harness to modern USCAR-style injector plugs used on LS2, LS3 and LS7 injectors. They simplify installation, preserve OEM connectors, and make it easier to revert to stock components later.

How do these adapters fit my GM truck's wiring harness?

The adapters accept the factory Delphi mini connector on one end and present a USCAR (EV6) plug on the injector side. That means you can plug directly into newer-style injectors while keeping your factory harness intact. No soldering or complicated rewiring is required for most installations.

• OEM-style Delphi mini connector mates to 1999+ GM truck harnesses
• USCAR/EV6 plug matches LS2, LS3, LS7 injector pins
• Sold as a complete set of 8 — one per cylinder on V8 engines
• Simple plug-and-play layout reduces installation time

Will these adapters work with LS2, LS3 and LS7 injectors?

Yes — the injector-facing side is the USCAR standard used by LS2, LS3 and LS7 injectors, so they physically and electrically match those patterns. They are intended for fuel injector models that use the EV6/USCAR connector style. Confirm connector shape against photos to ensure compatibility before ordering.

• Designed specifically for USCAR / EV6 injector connectors
• Compatible with common LS2, LS3, LS7 injector pinouts
• Verify injector end shape with product images prior to installation

Do I need any tools or splicing to install these adapters?

Most installs require only unplugging the factory Delphi connector and plugging in the adapter; no splicing, crimping or soldering is typically necessary. However, basic tools like pliers or a pick can help release OEM locking tabs, and dielectric grease is recommended for moisture protection. If your harness has been modified previously, additional wiring work could be required.

• Plug-and-play connection for untouched factory harnesses
• Tools only needed to release OEM clips or trim harness tape
• Dielectric grease advised for long-term corrosion prevention

What’s included and how many do I get?

The package contains eight AUTOKAY fuel injector adapters — one for each cylinder in a V8 application. That quantity covers full eight-cylinder conversions and avoids mixing connector types mid-engine. Each adapter is produced to match the factory harness on one end and the USCAR injector on the other.

• 8-piece set: complete V8 coverage
• Each adapter has Delphi mini (harness) and USCAR/EV6 (injector) ends
• Packaged ready for direct replacement or upgrade projects

Who this is for: These AUTOKAY adapters are intended for technicians, mechanics, and DIY enthusiasts performing injector swaps or LS-series upgrades on 1999-and-later GM trucks. They suit anyone who wants to retain the original vehicle harness while fitting modern USCAR/EV6 injectors — ideal for engine swaps, performance upgrades, or repairs where preserving OEM wiring is a priority.
