AEM VCU 300 LV Front Harness - Universal
AEM has built its reputation on precise, motorsport grade electronics, and the wiring side of any control unit install matters just as much as the hardware itself. The AEM VCU 300 LV Front Harness (SKU 30-8603) is the front side connector harness for AEM's VCU 300 LV control unit, giving you a clean, factory quality wiring interface rather than having to source and pin your own connectors.
This listing covers the universal AEM VCU 300 LV Front Harness, suited to any installation running the AEM VCU 300 LV control unit. As a universal part it isn't tied to a specific make or model, so it suits standalone wiring, custom looms and motorsport builds where the VCU 300 LV is being fitted outside of a factory harness setup.
Key Features
- Front side connector harness built for the AEM VCU 300 LV control unit
