i have a 2011 tahoe ssv. (police). it has lights and sirens installed as well as a viper remote start system by previous owner so dont know wiring details from the install. i bought the harness from @Zebrafive (thanks), a steering wheel from a junkyard escalade, and a new SIR from ebay. first problem was the empty slot that the harness for the heat was supposed to go to already had something there. maybe something to do with the viper system or the emergency equipment. i unplugged it to experiment and plugged in the harness from zebrafive and reconnected everything. the controls all worked (volume, cruise etc) but the heating icon wouldn't light up and had a message on dash about service trailer brake. i disconnected the heating harness and plugged what ever was there originally back in but im still getting the service trailer brake message. any ideas? thanks

anyone still selling the harness?
