So I got a 2003 Subaru wrx and my speedometer don't work or odometer. It got codes for P0502 which is speed sensor circuit low I replaced the speed sensor and cleared codes but it still doesn't work and the code is still there. So at this point I have no idea what to do. please help

See if the harness atop the gearbox is connected and secure.

Do you think I should take the cluster out and see if it's hooked up ? The harness seems fine
Yes, that's easy to do.

Would replacing the ecu do any good ?
Do not consider this. Instead, see if the harness to the ECU is OK instead. Follow the wiring from the speed sensor to the ECU. I believe the ECU itself is unlikely to be the problem.
