This wire draws the most amperage (e.g., a 240-watt Roadshock bar draws 20 amps). Do not run this directly to a dashboard switch or it will melt.

Roadshock light bars are typically sold with a pre-assembled relay wiring harness. The diagram below illustrates the correct flow.

This report covers wire color codes, function identification, standard relay harness integration, and troubleshooting common connection issues.
