like it says does any one know or have a diagram on how to hook up a btm vortec box i think mine might be hooked up worg cous my car pops under boost i bought it new from a guy who used his old msd btm and didnt have the instructions with it .
i check the timiing it's set to zero with spoute out and checked the plugs gapped at 028 autolite 23's .
i called up msd cause i know its the same company for the vortec box but the picture doe'nt look clear on what they sent
