Hey, Im having issues with my 1990 corvette not wanting to start, I've tried/checked everything. And to mwke a long story short ive come the the conclusion that I need to by vats at the ccm. I saw your post on here from a while ago where you made the square 30hz pulsing signal, and Ive already made the box, I just need some help as to where to hook it up to I've scoured fourms for hours looking for diagrams and such on where to conect it to. Im very new to all this and was wondering if you could tell me how you connected yours. Thanks and anything will help because im pretty much lost on this issue
