Yes, you wire it directly to the battery. The leading ignition only has 1 coil, but the trailing has 2. So if you do the leading you need 1. If you do the trailing you need 2.

It means, you need 1 coil with 2 outputs for the leading side and 2 coils with 1 output each for the trailing side, right?

And how much do we pay for one of them?

If I just do one side, I guess the leading would be better for both economy and power. ???[/quote]

The leading plugs fire at the same time. So you just need 1 igniter. MSD 6A's are about $150 each. If you want to try it out then do the leading first.

Yeah, I've seen on a web site that 1 red box replace the igniter and you get 2 coils with the kit. At first look it seems to go like that. Or you can only replace the igniter?
