Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- GM LQ4 and LQ9 engine harness applications with Delphi/Multec injector connectors
- GM 4.8L, 5.3L and 6.0L Gen III truck-engine harnesses with matching Delphi connector
- LS1, LS6 and LT1 EV1-style fuel injectors with matching two-pin plug
Product Overview
An LS swap or injector change can stop at one small mismatch: the truck harness plug does not fit the EV1 injector. These plug-in pigtail adapters bridge that connector difference without cutting all eight injector wires from a usable harness.
Connector direction matters. This set is for a Delphi/Multec-style truck harness going to EV1-style injectors, as shown. It is not the reverse adapter. Compare both male and female ends, latch location, terminal count, wire polarity, injector height, rail fit, and calibration needs.
Key Features & Performance
- Eight adapters for a V8 injector set
- Converts compatible Delphi truck-harness connectors to EV1 injector plugs
- Avoids permanent splicing of the main harness
- Short plug-in leads simplify injector swaps
Common Uses
- Installing EV1 injectors on a truck LS harness
- Completing an LQ4 or LQ9 swap without cutting injector wiring
- Correcting a connector mismatch after an injector upgrade

Frequently Asked Questions
Q: Do these make any injector work with my engine? A: No. They solve a connector mismatch only; flow rate, impedance, height, rail, seals, and tuning must also be correct.
Q: Are eight included? A: Yes. The set is intended for eight injectors.
Q: Can they be used in reverse? A: No. Choose the adapter direction that matches the vehicle harness and injector connector.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
