Ok so I bought a used set of passing lamps for my 2012 street glide. I haven’t opened up the faring to install yet, but I’m trying to figure out what I will need? I have the aux switch on the dash (unused) I was under the impression that it was a simple plug & play directly to the aux switch. But I’m hearing different, everything from I will have to unpin wires to I need to buy a different switch & harness?? Has anyone installed passing lamps on a streetglide that didn’t come factory with them that can give me some insight on what I will need?? Thanks
