I don't know exactly, but on the Trans-AM's with steering wheel
controls I believe used different resistances. Someone (Keith L,
www.ws6.com) reverse engineered the stero controls (to use to
activate nitrous). There are probably some archives about his
discussion on the f-body web site (www.f-body.org). I seem to
remember some pretty good details about who it worked.
I did not find anything listed about what he did on www.ws6.com, but I
am sure someplace in the archives (on the f-body group) there will be
some discussion of who it worked.
