Sent Rick a pm a few days ago about this very thing (to cut wire or not) and he was great -- cleared things up for me quickly. Thanks Rick!

But now I have another question I'm hoping someone out there knows the answer to. The driving light/turn signal harness has two connectors on the end that goes inside each mirror housing. Does anyone know where to cut these off and how to tap into the pre-existing connector inside each mirror. Guessing you need to use a butt end heat shrink style connector for each of the three wires but not sure. Honda dealership could offer no useful advice whatsoever.

Thanks!
