Default Battery hooked on backwards 2011 Lexus is250.

2011 Lexus is250. Was out of town and let my mom use my car. She got a friend to change the battery and he connected battery on backwards. Car wouldn’t start. Blew the fusible link. I swapped the fusible link yesterday, car started right up. Dash is lit up like a Christmas tree now. Power steering doesn’t work, windows won’t go down, check engine light on,no abs, radio won’t turn on, display won’t turn on, etc.

You've got a long way to go checking fuses, validating wiring and scanning modules. Good luck.

Although I wouldn't recommend driving it without power assist, you need to read the codes from the various on board computers.

On a 1 to 10 scale, how certain is the workmanship in this repair? Can you share which links blew? 9 out 10 times the 80A power steering link is toast. Usually there are not this many issues? What is the battery voltage after starting? If low and under 12.0, the incident could have taken the alternator out. Start with system health check and do a search, you are not the first unfortunately.

PS look here, phone app $40 you can read codes.
