I'm really dreading this. Mostly because I've never tried it. I'm wondering what the main differences are between the kits. For instance, when someone says that an AAW kit terminates it's wires, what does that really mean? Do they just add terminal ends or is there something else like specialized ends that'll cost me extra to add to a cheaper EZ kit? And if they just add terminals (like spade connectors) why are they so much more than say an EZ kit? In the end, will it cost me just as much or more to go w/an EZ kit @ $185 vs. a $500 AAW or Painless due to missing parts? How "universal" are these Painless universal kits. Are they so much so that they don't fit anything well? I have a factory manual with all the wiring diagrams since I know that's the place to start. I'm keeping my car as simple as possible since it's my first build. I won't be aading power window/locks etc. but I will be adding a/c and a sat radio set-up. So, how many circuits will I really need? Thanks for being patient w/a newbe.
