after a install off a torsen t-2 spec stage 2 clutch and fidanza flywheel my abs light is on and my speedo if off a bunch. what could it be? does abs control the speedo?

also when car runing in nuetral i hear a chatering sound from trany and when i press in the clutch it goes away. is that normal till break in period, i did buy a ford slave cylinder from bill and i used all torque specs from ford.

i used a new speedo gear and made sure it was seated right
