Fried my mpx driver side box bought a used one at a junk yard , when I turned my car back on my cluster is dead all lights except for the battery light . Steering wheel tilt dead ,Windows and memory seat .
Yes I researched my alternator fuse is good .
I guess my question is does the mpx box have anything to do with the cluster ? And is there anther computer that got damaged ?
Thanks in advance

You must be another poor guy who doesn't know that the MPX door computer shares the same fuse with the meter unit. Check the fuse "10A Meter". Without removing the battery terminal, you must have done the replacement. You should not remove/install electrical units that are supplied the 12V even when the key is removed.

Yes sir poor me . I wouldn't be asking the pros if I knew .
Thank you kind sir ! the fiat 500 is back 🤘🏻

Glad that your car is back.
I know you are smart and not so poor since you were the guy who replaced the MPX box finding that it was a fault. It would be smarter to do the electrical job after removing the battery terminal to avoid problems.
