This might be a hard question to answer, but i found a 2002 Mac Tools Gator Nationals 5" tachometer. Its brand new and was still in the box. I'm thinking about putting it in my car but i don't know how to set the DIP switch on the back of it. there is 6 switches on it. I've been all over the net searching and trying to find out what to set it at for a V8 but i haven't had any luck. Do any of you guys have this Tach or know how to set them?

Thanks
