/en/qa/tag/molex Powered by Question2Answer /en/qa/108168/start-x-harness-taps-into-only-bcm-why-does-the-nist1-require-so-much-more I&#039;m confused about why the evo-all with the NIST1 harness has so many unterminated / spliced / molex connectors, brake switch replacements, start button replacements, obd port replacements... yet doesn&#039;t use the BCM harness for any of these functions? <br /> <br /> The start-x harness needed none of these connections. The guide also isn&#039;t clear about what wires are simply orphaned or why there are molexes on some at modular connectors that already have factory wires.
