Autel OBDII Diagnostic Test Cable 5.6 ft 16‑Pin OEM — Screw‑Lock Connectors, Stable High‑Speed Data

The Autel Original OBD2 Main Test Cable is a 5.6 ft OEM diagnostic lead that links compatible Autel wired scanners to a vehicle’s OBDII port for stable, high-speed data transmission.

This genuine Autel 16-pin main test cable is engineered to provide a reliable, plug-and-play wired connection between select Autel handheld scanners and modern vehicle diagnostic ports. With a longer 5.6-foot length, secure 15-pin-to-16-pin wiring, and screw-locking connectors, the cable eliminates typical wireless dropouts and gives technicians room to move during troubleshooting, coding, or ECU programming. It’s designed for workshop durability while keeping installation simple.

Which Autel scanners work with this main test cable?

This original cable is intended for a defined set of Autel wired scanners and supports full diagnostic functions when paired with compatible models. It connects scanners that accept a dual-row 15-pin scanner connector to standard vehicle 16-pin OBDII DLCs.

• Compatible examples: MK808, MK808S, MK808Z, MX808, MX808S, MP808 variants.
• Also fits: DS708, DS808 series, DS808K, MS905, MS906, MS908.
• Immobilizer/advanced series supported: IM508, IM508S, IM508 PRO.
• Always confirm your scanner’s connector type and model before purchase.

How does the extra-long 5.6 ft cable improve diagnostics?

The extended 5.6-foot length frees you from being cramped at the steering wheel and makes it possible to run tests from outside the cabin or move around larger vehicles. Longer reach helps during road tests, component access, or when the DLC is tucked under trim panels.

• 5.6 ft (1.7 m) length for greater mobility in garages and on-road diagnostics.
• Allows easier access to vehicle components while remaining connected.
• Reduces strain and awkward postures during prolonged diagnostic tasks.
• Better ergonomics for bench testing or console-mounted units.

What are the build and connector details I should know?

The cable uses a dual-row 15-pin connector to mate with the Autel scanner and a standard 16-pin OBDII plug for the vehicle DLC, with screw-fasteners to secure the connection. It’s built to maintain stable data transfer and resist interference common to wireless links.

• One end: dual-row 15-pin plug that secures to Autel scanners with thumb screws.
• Other end: standard OBDII 16-pin male connector for vehicle DLCs.
• Durable jacket and strain reliefs for workshop use.
• Wired connection reduces disconnections and improves transmission stability.

Which vehicles or setups is this cable not suitable for?

The cable is not a universal lead and excludes many Autel handheld families and certain vehicle interfaces. It is not compatible with specific Autel models, FCA Chrysler-family vehicles without the Chrysler 12+8 adapter, nor with some VCMI J2534-type modules.

• Not for Autel handhelds such as MS309, AL519, AL619, ML519, ML629, TS series.
• Not compatible with Autel Ultra, MS919, MS909 Elite II, IM608 PRO II families.
• Not intended for Chrysler/Dodge/Jeep/FIAT/Alfa without Chrysler 12+8 cable.
• Not a replacement for VCMI or J2534 programming interfaces.

Who is this for? The Autel Original OBD2 Main Test Cable is aimed at professional technicians, mobile mechanics, and advanced DIYers who use compatible Autel wired scanners and need a dependable wired connection for diagnostics, coding, or ECU programming. Buy it if you require a workshop-grade, interference-resistant lead with extra reach and secure screw-lock connectors. If your scanner model or vehicle requires a different interface, consult Autel support or choose the correct adapter before ordering.
