Default Tach not working?

Pulled my hooker long tubes and put the stock ones back in. Pulled the K member off to do this installed every thing back on and the tach does not work. I know what wire it is comeing off the computer and i use a meter to test it and there is no signal. WHat could it be the only wires i unded was the ones needed to remove k member.

Check the grounds at the back of the head and the harness in which those grounds run into.

my tach also stopped working, and it threw a P0345, something to do with the Camshaft position sensor, do you think my harness is bad? because the tach will occasionally work for a few seconds, then crap out.

also, what side of the head is the harness on, and where are the grounds?

thanks for the help
