Ditto here. The amp multilock 12 pin connector 105B, is only wired for Aux & cruise control for the 2011 CV SG. I had to make my own harness from from 105B for spot lights. Additionally, I bought the Boom Audio kit with the CB module & non ultra overlay harness. Exact same thing happened with the speaker wire switch. The wires aren't there coming into 105B and the kit instructions say nothing about it. I had to solder one wire that Ts off of an existing wire in the back of the radio and go into 105B and make two other wires that go from 105B into the right side plug on the radio (I have my manual in my garage, but I think it's connection 27 that plugs into the right side of the radio, a different type of terminal end than multilock).
