I called the Vintage Air people and they said that the 1969 Firebird's kit uses the cables and not electronic. Which I knew but they also said that if you get that kit it will probably be replaced in the future for an electronic version and you won't be able to get parts.
So then I am suppose to try and look at an electronic version. Either the 1969 Camaro or a Universal Kit. Both will take adapting them and relocating a controller somewhere.
