Anyone interested in helping out with this project?????

 

Sure why not. In in killeen.

 

I've no idea where that is (!), but contact Guy. You can find his email address at www.Z-Xtreme.com or pm him through the forum (user name "insaneamine").

 

Maxground already has an '07 grounding kit available now for three weeks. Turns out the newer cars already have bigger wires, so the grounding kits for the newer engines is also of a larger gauge. His ID on the forums is z327.
