Anyone know how to wire up the air con thats in my car at the min? im putting in a fully rebuilt redtop but want to keep the air con. someone once b4 said to me that a wire would need grounding? Also whats the breather mod all about? what does it involve? Does magnex make a s/s cat back system with 6x4 tailpipe for a phase 2 hatch? (to go with new engine) sorry for all the questions and thanks for any help, Neve'o
