Hello,

I am a new owner in the US. The bike is a 1992 Rothmans SP. I am in the process of a bottom end rebuild. While working on the bike I've been trying to learn as much as possible hands on and through the web. Anyway, I noticed this Black HRC box next to the PGM Box. The wiring harness goes through the HRC box, and the box says Not For Highway Use. I've read about a HRC Harness, could this be it? And what effect does it have on the bike?

Thank you
