Probably the hardest part is getting the wire through the firewall to the dash. I'd have to look at mine and see where I ran it as I did it so long ago.
FYI, if you do install a 2 or 3 gauge A-pillar cover you WILL loose some of your sightline to the left. Not much, but it's there. You get used to it. I will say it's really nice to be able to just glance over at eye level and know if there is an issue or not.
