Just got back from the cold garage, since when is the "top of the steering column" on the bottom or in this case the right side. Well at least I now know where the Pats transceiver really is. Jason if you didn't have the bottom half of the steering column cover off forget about that area. And this antenna thing well it's not something you can unplug? It's part of the transceiver plastic assemby. Sure glad I'm not a mechanic, who writes these manuals?
Actually it's fits around the key cylinder with the ckt board hanging underneath and one machine screw holding it place on the top of the bottom side of the column? $99 bucks Jeeze!
So I can't see any problem with running speaker wires or whatever in the dash interfering with the transceiver. The only area is right there around the ignition key cylinder.
Key when inserted can't be more than 3/8"-1/2" from the xcvr's ant.
Go to know what's really where, hopefully if I get boned-up on the system mine won't break!
I still have a thousand questions of my own to answer.
As far as your original question,I haven't got brave enough yet to try experimenting with pin 3.
