96 deville steering wheel control retention adapter. It gives me a basic description of what to do but I would really appreciate some feedback from someone who has done this before. Do I really have to tap it right near the steering column? Which harness? :hmm: I already have the other important adapter to make it work and I'm sure it does not have the amp. So yeah, I'm going to go in there and try to make it work today so I would appreciate any info you have. Thanks.
