Ok i did the conversion, and now the brake light is on.
I bled and i rebled the brakes, went thru 2 large bottles of fluid.
What did i miss?
Do the old connectors from the powermaster need to be plugged in, or fuse pulled ?
Otherwise the brakes feel good.

If the switch is off the system and the connector is not grounded on anything the light shouldn't come on.

Problem lies in the parking brake sw. doubtful.

Or lies in the brake warning switch built into the proportioning valve. You did install the brass one, right?

Could be unequal pressures front to rear which I think operates that switch. Try taking the wire off that and see if the light goes out. It activates with a ground on the lamp. Key on engine running of course.
