Not incorporate the Hella-provided relay as standard. After some testing, we determined that the additional few dBs offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness using the relay, inline fuse and additional wiring directly to your battery.
Should your heart desire those last few ounces of dBs, our harness can be adapted for use with a more complex relay harness.
