He can't just splice the modulator into this inline harness ? It should then modulate everything downstream of the inline harness. It has been a while since I was in there so I can't remember all of the details.

Thanks guys. I'm not planning on adding any lights, just want to modulate the OEM brake light. I put one of these on my Valkyrie years ago and it was a pretty simple task since the wire was easily accessed behind the right side panel. This F6B is a different beast to work on. I appreciate the link to the Kury harness, I'll figure something out. I've got all Winter.
