Product SKU: HDT SUBHARNESS
Take full advantage of the capabilities of Hondata's S300 or K-Pro with this expansion subharness. This subharness plugs into your Hondata S300/K-Pro onboard analog/digital expansion connector and provides a connection to additional inputs.
This is the exact same harness that is included with a new S300 or KPro system. If your existing harness is damaged or goes missing, this harness is the perfect replacement.
