But i presume that by asking this question you are not particularly good? If you are a complete novice, take it to a garage and pay them, if you can work stuff out and know which way is tighten and which way is loose then do it yourself.
I had it fitted without EDFC. Unless U got strong arm physically fit, I say that U get it fitted by the shop. U also need many other equipments to do this job. Since I live in Thailand, the labour is much much cheaper, fitting cost is not an issue over there. The shop that sell U the stuff will fit it for free.
