My 2002 had ABS that was disabled. Fuses pulled and no dashboard warning light.
Easy peasy, and no repercussions.
Not sure if he pulled any relays, watch doing that as some relays may share circuits.
The PO replaced the Dana 30 with a non disk brake Dana 44. Also removed sensors and wires without issue.
Brakes worked as good as stock brakes do.
But I upgraded to BMB’s and a Dana 44 with disc brakes.
And NOW I have brakes!
And no warning lights.
