ok

any hydraulic fluid will do (NOT LHM )

they are the same switch (its in the wiring that differs)

also to mount it (if cab had electric roof from factory there is 2 threads in boot ) then you need a bracket that mounts on these and to pump

if not then you need to sit pump in boot passenger side

wiring does only work in pos1 unless (iirc its the yellow) relay from under dash is removed

manual roof pins have ball joints on end

electric roof pins (are pins and circlips)

the rear passenger panel is different has a cut out for pump and a separate cover that pressed studed on

hope this helps
