Don't let the instructions intimidate you, the install is so easy a cave man could do it
Agreed. The install is really quite easy. You just need to go into "zen" mode and take your time being calm. I find that a shot of Petrone, a Corona and one of my wifes Xanax pills helps. The people at HD that write some of the factory install instructions should be phased out of the living carbon based unit club.
If you have a problem, your best bet is to ask here or on one of the other HD forums that provide a wealth of knowledge.
