Main Harness DBW (Series B)

Complete main electrical wiring harness for the Rush SR DBW (Drive-by-Wire) cars. "Series B" refers to the DBW version of the harness. This harness is the central nervous system of the car's electrical network, connecting the battery, ECU, dash, sensors, switches, and all major electrical components.

The main harness routes power from the battery through the master switch to all systems, and carries sensor signals back to the ECU and dash. It includes properly terminated connectors for the shift harness, front clamshell harness, steering wheel harness, and other subsystem harnesses. Pre-terminated connectors eliminate splicing and ensure reliable connections in the high-vibration racing environment.

This is a complete replacement harness if your existing main wiring has been damaged or if you're experiencing electrical issues. Includes technical routing diagram. The DBW (Series B) version incorporates improvements and updates from earlier harness designs, including support for drive-by-wire throttle control.
