Tach plus Holley Avenger EFI - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am hooking up an avenger efi to my 350. I am going to use a GM small cap HEI so the computer can control the timing. This is a picture of the holley wiring schematic. Where can I hook up my tach? Can I hook it up to the (-) side of the coil or tap into the yellow crank input?

Thanks!
