Take a look at his profile. He's got a 2001 ETH/6-speed.
Don't use the scotchlock tap that comes with the Comp. There have been MANY cases of wires not really getting tapped, kinda tapped, or (in my case) intermittently tapped.
My new favorite method is the Swenco Posi-tap. It's a toolless, weather resistant, very positive connector that performs the same funciton as the scotchlock (but actually works). Depending on how much time/money you want to spend, soldering or a stealth cover will work well too.
Level 1, tapped or not tapped, is just like the EZ. You may be able to run the higher levels, but the probability of your clutch hangin' on goes down exponentially as the levels go up. And remember, once you smoke it from excess power it will never be the same again.
The decision to tap the wire or not is a funciton of your self control and your clutch budget!
