What sort of advice?
I've never done a 200Tdi, but I can't imagine it's much.
Glow plugs, starter, temp and pressure sensors?
Starter can use SII wiring (though I'd put in a larger cable for the motor, 1/0 or 53mm2).
Senors should be able to use the same wiring if electric (I prefer mechanical however).
Glow plugs should be run off a relay and you can either get a proper Land Rover diesel switch or just use a simple push button switch (I did the latter).
Four wheel drive allows you to get stuck
in places even more inaccessible.
