Hi
The worse place Toyota could have placed the relay signal flasher for tarago/previa vans 1990-2000 models, is behind the dash.
Once you remove the dash there is a wire attached the bottom of the dash board which is connected to the column gear shift, be careful not break it.
You have to disconnect the 3-4 wires and put them back in the same order and undo the screws to separate it from the dash board.
You have to separate the signal relay by un-clipping one side and then the other side, pull it hard to separate it and then it will come free then you have to push it back together so its one piece agains
Cheers
