It uses the 3-pin link to deliver data for oil pressure, coolant temp, fuel pressure, oil temp, and tach—exactly what you want to see on a high-output setup. Out on the water, it keeps those readings steady and includes transient-voltage protection to help shield the PCM. It’s built for race engines using a Vessel AGI and works across all PCM families.\u003c\/p\u003e\n\u003chr data-start=\"561\" data-end=\"564\"\u003e\n\u003cp data-start=\"566\" data-end=\"1096\"\u003e\u003cstrong data-start=\"566\" data-end=\"582\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"582\" data-end=\"585\"\u003e    • \u003cstrong data-start=\"611\" data-end=\"631\"\u003e3-Pin Gauge Link\u003c\/strong\u003e – Sends core engine data straight to the gauges.\u003cbr data-start=\"680\" data-end=\"683\"\u003e    • \u003cstrong data-start=\"709\" data-end=\"733\"\u003eRace-Focused Signals\u003c\/strong\u003e – Oil PSI, coolant temp, fuel PSI, oil temp, and tach.\u003cbr data-start=\"788\" data-end=\"791\"\u003e    • \u003cstrong data-start=\"817\" data-end=\"840\"\u003eVoltage Suppression\u003c\/strong\u003e – Helps protect the PCM from electrical spikes.\u003cbr data-start=\"888\" data-end=\"891\"\u003e    • \u003cstrong data-start=\"917\" data-end=\"942\"\u003eVessel AGI Compatible\u003c\/strong\u003e – Designed for performance-minded installations.\u003cbr data-start=\"991\" data-end=\"994\"\u003e    • \u003cstrong data-start=\"1020\" data-end=\"1049\"\u003eOEM DTS\/SmartCraft Layout\u003c\/strong\u003e – Uses Mercury’s correct pinout and shielding.\u003c\/p\u003e\n\u003chr data-start=\"1098\" data-end=\"1101\"\u003e\n\u003cp data-start=\"1103\" data-end=\"1339\"\u003e\u003cstrong data-start=\"1103\" data-end=\"1134\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1134\" data-end=\"1137\"\u003e    • All PCM families\u003cbr data-start=\"1179\" data-end=\"1182\"\u003e    • Race-engine applications\u003cbr data-start=\"1232\" data-end=\"1235\"\u003e    • Setups using Vessel AGI\u003cbr data-start=\"1284\" data-end=\"1287\"\u003e    • Performance gauge clusters\u003c\/p\u003e\n\u003chr data-start=\"1341\" data-end=\"1344\"\u003e\n\u003cp data-start=\"1346\" data-end=\"1772\"\u003e\u003cstrong data-start=\"1346\" data-end=\"1382\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1382\" data-end=\"1385\"\u003eThis harness keeps critical readings tight and predictable, which matters even more when you’re running a boat that doesn’t live in the low RPM range. The clean signal path helps gauges react quickly and keeps them from flickering when the engine shakes or loads hard. It also simplifies the rigging since you’re pulling everything through a proper 3-pin link instead of mixing adapters.\u003c\/p\u003e\n\u003chr data-start=\"1774\" data-end=\"1777\"\u003e\n\u003cp data-start=\"1779\" data-end=\"2104\"\u003e\u003cstrong data-start=\"1779\" data-end=\"1794\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1794\" data-end=\"1797\"\u003eOEM race-engine wiring keeps the signals clean and the PCM protected. The connectors fit tight, the shielding works, and the pinout is exactly what the PCM expects. Most boaters running performance setups stick with OEM because off-brand wiring can cause data glitches you really don’t want on a race motor.\u003c\/p\u003e\n\u003chr data-start=\"2106\" data-end=\"2109\"\u003e\n\u003cp data-start=\"2111\" data-end=\"2275\"\u003e\u003cstrong data-start=\"2111\" data-end=\"2118\"\u003eFAQ\u003c\/strong\u003e\u003cbr data-start=\"2118\" data-end=\"2121\"\u003e\u003cstrong data-start=\"2121\" data-end=\"2168\"\u003e1.
