Hey all, last year (2024) i manual swapped my 1992 toyota pickup 3.0 SR5 DLX and in the last 2 weeks i replaced my alternator and battery because voltage regulator had failed (the battery had gone bad due to sitting a shop for months without being cranked). In the last couple of days something strange has happened, when i start the truck the brake light, battery light, and A/T oil temp light come on and they wont go off until i turn the truck off. I dont know why its doing this, and i really need help figuring this out. Thanks in advance!

Note: this was my first time manual swapping a vehicle
