ok my 1990 ef b16 swap speedometer has never worked and i didnt do the swap but it looks like the speedo cable is broke off in the transmission.....its an ls tranny by the way but i was jus wondering if i, gonna need juss the cable or thatt lil boox thing aswell
thanx

 

u shud be using the speedo sensor instead of the cable in the first place. should have done it during d swap.

coz ive seen some ppl are facing d same problem as yours by maintaining d cable.
