Hy guys as i said in another discussion i mounted in this past week end this two very necessary objects
now the gear indicator function normally but there are problem with the rev counter....
after connecting the red-positive and black to ground,there are two wires coming out from the tacho orange and brown....i don't know what of these take impulse from the engine and i make tests but when i connect orange wire to pick up positive cable it lights on all led in sequence but this led don't follows motors rpm
when i connect brown wire to cable sometimes all the led lights together 
do you have any ideas???al suggestion are accepted
