well I reconnected the line cut to turn off the speaker and just ripped the speaker off the board. It seems now the ABS light and outside temp are working for me. Also the brake light is working properly. It does not show when I have the cruise control on but does show when it is set. The battery ran fine and got a good charge. One hint that I can say I noticed when I first had this connected with the wire cut was the windshield wipers were moving slower than normal
very odd but that would indicate this issue before you had the trouble of a drained battery.
So other than having to resplice that wire and trimming the connectors on the STI cluster I'd say it works great with my 05 automatic.
