Stu Posted March 25, 2009 Share Posted March 25, 2009 You don't have to do it exactly as per the diagram.. that's assuming you have NO loom in the car and you're doing it all from scratch.. Link to comment Share on other sites More sharing options...
Tez162003 Posted March 25, 2009 Author Share Posted March 25, 2009 Well I was hoping I could just wire into the existing loom tbh, why run new wires into the engine bay which are already there? How would you suggest I go about it? Link to comment Share on other sites More sharing options...
boostic Posted March 25, 2009 Share Posted March 25, 2009 Id get an exsisting diagram from whats already in the car and try and match it up to your diagram and see whats left Link to comment Share on other sites More sharing options...
Stu Posted March 25, 2009 Share Posted March 25, 2009 How would you suggest I go about it? I'd start by reading the entire megamanual, three times Link to comment Share on other sites More sharing options...
