Cruise Control Help, Installed a sterio and now cruise doesn't engage Options

[totalyout]

Need some help. I just hooked up my sterio. I used the adapter to connect to the factory wiring. Used the antanna remote wire to be the remote for the amp. This all bypasses the factory amp. After doing this noticed the the cruise control light will come on in the cluster, but it doesnlt seem to engage. Been running through a 96 Toyota wiring manual but can't seem to find anything connecting the two. By the way I'm the proud owner of a 94. After 10 years The airbags went off in a tiny fender bender and they totaled my 96. So now have a new project. Any help would be awsome...
