Installing cruise on an 06 SG, the last wire in the insructions is a "speaker switch" ground, "if the bike has a speaker switch". Does my bike have the speaker switch? I couldn't find it in the manual, but I did see a picture of the inner fairing cap with a rocker switch labeled "SPKR", is that it?. I hate to ask stupid questions, but electronics aint my strong suit, and I don't want to create any electrical problems. Thanks.
