6-Pin OBD1 to OBD2 Adapter Cable for Chrysler Jeep Dodge

Connect OBD1 Chrysler, Jeep & Dodge Vehicles to Modern OBD2 Diagnostic Tools

This 6-pin OBD1 to OBD2 adapter cable lets you use today's OBD2 scan tools on older Chrysler, Jeep, and Dodge vehicles that feature a 6-pin OBD1 diagnostic connector. If your vehicle's OBD1 system is based on the OBD2 standard protocol, this cable bridges the gap — saving you money on specialty tools and shop visits.

Made in Mainland China.

How It Works

On-Board Diagnostics (OBD) has a long history, and many early OBD1 systems were built on protocols that later became part of the OBD2 standard. This adapter takes advantage of that compatibility — one end plugs into your vehicle's 6-pin OBD1 diagnostic port, while the other end connects to any standard OBD2 diagnostic tool.

Frequently Asked Questions

Q: Will this OBD1 to OBD2 adapter cable work on my 1994 Jeep Cherokee?

A: It may work on a 1994 Jeep Cherokee if the vehicle has a 6-pin OBD1 diagnostic connector and its OBD1 system uses a protocol that is part of the OBD2 standard. However, please note that this adapter is NOT compatible with all OBD1 vehicles — the 1995 Jeep Grand Cherokee and 1995 Dodge Dakota are confirmed exceptions. We recommend verifying your specific connector type before purchasing.

Q: What OBD2 diagnostic tools are compatible with this 6-pin Chrysler adapter cable?

A: This adapter is designed to work with standard OBD2 diagnostic tools and scanners. As long as your scan tool supports OBD2 protocols and the vehicle's OBD1 system is built on OBD2-standard protocols, the adapter should allow communication between the tool and the vehicle's ECU.

Q: How do I know if my Dodge or Chrysler vehicle has a 6-pin OBD1 connector?

A: You can check your vehicle's owner manual or look under the dashboard near the steering column for a 6-pin trapezoidal connector. Many Chrysler, Dodge, and Jeep vehicles manufactured in the early-to-mid 1990s used this connector type. If you're unsure, consult a trusted mechanic or your vehicle's service manual.
