Mercury 2 pin diagnostics cable

Jaltest JDC614A9 — Mercury Marine 2-Pin (A9) Diagnostics Cable

The JDC614A9 is a genuine Cojali Jaltest diagnostic cable designed for Mercury marine outboard engines equipped with a 2-pin diagnostic connector, compatible with the Jaltest Link V9 interface. Mercury builds a wide range of outboard engines, and older or smaller displacement models often use a 2-pin diagnostic port. The JDC614A9 is the cable that gives your Jaltest system access to these engines.

Listed in the official Jaltest 2025 pricelist at $60 MSRP, this is the most affordable Mercury marine cable in the Jaltest lineup — and it covers a specific connector type that you cannot access with the 4-pin (JDC603A) or 10-pin MEFI (JDC604.9) cables. The "A9" suffix indicates V9 interface compatibility.

What This Cable Does

The JDC614A9 connects the 2-pin Mercury diagnostic port to your Jaltest Link V9, enabling:

• Fault code reading and clearing — access DTCs from Mercury outboard engine ECUs with 2-pin ports
• Live data monitoring — view engine operating data in real time through the Jaltest Marine platform
• Marine diagnostic functions available within the Jaltest Marine outboard software module

• Outboard Cable Kit — Part Number 70002010 ($475 MSRP)

Who Needs This Cable

Marine service shops handling Mercury outboard engines across multiple connector generations. The 2-pin connector is found on older and smaller Mercury outboards.
