Awww, your lucky though, at least the link didn't burn out on you while you were on a trip. Thats what happened to me at about 2 or 3 in the morning on my way back to TN... ended up on the side of the road in KY in the middle of the night... clueless as to what even happened. I didn't have a flashlight to see what all was going on
Get the fuse back in there... and you will regain power to everything. Most all your circuitry needs that fuse in order to even operate - I remember the only lights I got to come on were the ones on my doors.
Once the morning came around though - I could finally get in there and trace down the problem. I was lucky to have semi-decent knowledge in electronics.
Toyota dealerships can have you a new one with overnight delivery - its a really common fusible link.
