FAQ
Q: What is the difference between EV1 and EV6 fuel injector connectors?
A: EV1 (Jetronic) is the older 2-pin or 3-pin style used on Bosch injectors from the 1980s–2000s. EV6 (USCAR) is the newer 2-pin style used on most modern injectors. They are not directly compatible — adapters are available.
Q: Do terminals come pre-installed?
A: Terminals may be pre-installed or sold separately depending on the variant. Check the product listing for terminal inclusion. Use a proper automotive terminal crimping tool for field installation.
