Good morn. We are building a Tahoe soon and have already procured a new trio Valor bar. I’ve been told by more than one upfitter I’ve discussed the build with that’s it’s not possible to activate most of the features of the bar without a SmartSiren system. However, the FS sales rep assured me that’s untrue. Trying to get a straight answer in this as it would obviously affect which siren system is ordered. The bar would need to do normal mode 2-3 stuff, rear alternating flash, signal master in amber, flood and alley, and cruise modes.
