disconected the o2 sensor to take the header off to fix the bracket and the speedo just stoped working. checked all the wires all is good and conected. What could the problem be? It’s on a 00’ b16a2 less than 70k worked fine the other day.
double check your ground on your waterneck, sometimes they will break off 1 wire at a time
either that^^^ or the pins pull loose
ok i’ll check those as soon as the car cools down.
