Hello,

Since those lights were not on before changing out those components, it is likely that the ABS/wheel speed sensor got disconnected or could have pinched wires.
Inspect the ABS sensors. Make sure they are connected and secured.

It will also be a good idea to scan the ABS system for trouble codes, as it could point the issue.

I have attached the ABS sensor diagrams for your reference.

Please let me know if you have any questions.
Thank you.
