I just installed a tko600 in my 70 and can't get the speedo to work. I can jump it manually by hand. The adapter is on right.. I dont know. I hope its not the tranny- that would suck............ any ideas

joe,
are you referring to a mechanical or electronic speedo?

Joe;

Are you using the adapter from Fourte, or the conversion speedo cable ??

if its like the one i had, the adapter they give you wont work-the factory cable wont reach into the adapter enough to fit into the square hole-i had to get a cable already made up with the adapter made on to it-hopefully, they have an adapter that works now with the stock cable, because its not fun replacing the cable @ the head

its the forte adapter
