87 4runner marker lgts always on

[MAS904]

The marker lights are always on dim.
They do light to full intensity when turned on.
The Haynes book does not show lighting diagrams in much detail.
With head light switch disconnected, they still light.

Any suggestions would be appreciated.

Haynes book are a joke when it comes to wiring on Toyotas. Need the FSM for an accurate schematic.
