V6 is what I have as well, and just tapped the ground for the #1 fuel injector. It is pretty tight area but you can pull the electronic plug and tap it. You have to tell the window switch that it is a waste spark ignition so that it properly reads the RPM's. When you say it is "pre programmed" does that mean someone already set it up for the waste spark ignition and set up your RPM window?

As far as plugs, the V6 already runs a colder plug so unless you are going to run a big shot the stock plugs should be fine. I run a 75 shot and the plugs after one season looked almost new still.
