Its lots of work!
Firstly, need to check if your dash loom has the wiring, I can't remember which relay it is, but it will be easier to undo the bulkhead connector and look for the pins, if it has the pins, happy days, it'll be easy...ish.
Other things you'll need is the larger twin pump washer bottle (and both pumps, they are different to non-sport), and plug for the headlight washer pump (its the same for the windscreen washer pump so that helps) obviously the pipe, can use normal windscreen washer pipe, although get yourself some one way valves, your bound to need them at some point with these washers, and you can fit them in the passenger arch so you can remove the bumper easily.
routing the pipes is easy enough, theres a grommited up hole in the inner wing next to the screenwash bottle that I used, I did also remove the inner arch liner for best results.
Hardest bit is what I touched on earlier, if you've got the pins, you need to route the wiring for the new headlight washer pump plug through the big rubber cover over the bulkhead connector, and put the pins in, assuming your dash loom has it. If your dash loom hasn't got the wiring, it'll be best to fit a relay in the engine bay fusebox.
Headlight washer pump wiring is pin G1 and G2 below, viewed from the engine bay side of the dash loom plug in the bulkhead (known as the R107 connection)
After all this, it will also need coding in Clip, You should be able to find somebody to do that cheaply though as it takes litrally 5mins.
If you need any more help, give me a shout. Shame you're not local as I could do it all easily!
