I just bought a viper 5105 remote start for my h2. Has anyone done an install yourself? Id like to hook up the heated seats to it also. I bought an Xpress kit box that they said was required for the cadillac and H2s. But I also saw that there is a t-harness for some autos but couldnt find one for the H2. Does anyone know where I can get one or if one is even made? Im fairly good with mechanical things and can usually figure out wiring if the instructions are good but Im alittle nervous about this project. Any pointers or help would be GREATLY appreciated
