I too have an 04 TB EXT LS for my wife's DD.

I can't help you on the electrical problems, but THESE guys can.

I recently found and signed up with trailvoy.com. It's like TYF but for the 360 platform.

Check it out, I'll bet those guys can/will help you. Just expect a little bit of razzing from them though. They are not as nice as the TYF guys.

EDIT: Trailvoy has owners manuals and wiring diagrams etc for your truck. They may help you as well.
