Angry No tach operation!!!!!

I've got a 2004 electra glide classic. Problem is my tach doesn't work. I checked the signal to the ecm and it's seeing a signal. I bought a HD factory service manual to trace out the electrical system. I have wire continuity from the ecm to the cruise control module. But i can't figure out which wire runs to the tach to control it. I tried a different cruise module, but that didn't work. help!!!!
