Handbrake light always on!

I've honestly searched everwhere and checked everything

> brake fluid is at the max
> brake discs/pads are fine.. like new tbh
> changed the reservoir cap with the wires and the sensor float
> checked handbrake switch, the light dims when handbrake is down but doesnt go out

any ideas?

fixed! turned out that the abs ecu was still plugged on even though it had an ek9 non abs prop valve
