I am chasing the face plate(incab) with both switches as well as a vacuum servo/activators.
2x Vacuum reservoir
1x Vacuum servo/activator
2x inline Check Valves
1x Face plate with both switches front and back diff operation
There is probably more but this is needed at present.

Also does anyone know where to buy water hoses for my T3, or who stocks them, i have hit a wall.
Thanks
U2U if like or hit me back here.

What water hoses are you after ?
