Thanks. I haven't had much time to do any real troubleshooting, but I think that my problem is in my wiring (could be just a fuse). Neither my new TCU nor my original one shows up when I run diagnostics. If spring ever arrives, I'll get my multimeter out and check for power, CAN signals at the connector and work from there.
