will i have a b18c gsr on a b16tranny in my EG hatch , and my speedo gauge doesnt work, but my rpm gauge does work and every other gauge works except for my speedo so my question is could it be my speed senor or the actual connector piece that connects to senor, before the speedo use to jump around from 0 to 40 to 100 etc.. so i figured that the connector teeth could of snapped or something and cause a short circuit with would make it jump like that but i dont know or is the cluster just bad..??... and now it just doesnt work, what could be the problem i dont want to go out and buy a new speedo if i dont need it ya know i hope someone could help me out.. thanks
