That reason is that they dont want to be held responsible for unqualified persons wiring their machines dangerously or incorrectly!
It seems you have sourced a board (which you will need) and a loom (which you wont need unless your machine is wired with an old RL-30 Gicar board.
Might I suggest the best source of information might be the organisation from which you sourced the parts?
If you are unsure of what youre doing, do pay a tech for the 20-30 minutes of his time this job will take. Better safe than sorry. You will also retain the 3 month warranty provided by the parts supplier on the board if you have it professionally installed.
