    Got everything hooked up,
    Red wire onto the Cigar Mirror (15 Amp fuse)
    White wire onto Illumination Fuse (15 amps fuse ?)
    Black wire onto Ground
    GREEN WIRE.... this MIGHT be the Problem but i am not SURE if it is cause it does work, it Rev's and all but it will NOT Link up with the Actual Revs, For instants (actual Revs 4,500 and on the Tach it would say only 1500) 0_o? WTF!
    Splice Mechanism that was Provided, spliced it with the Yellow/Red lined Ignition wire that was coming out from the Spark plug unit. So i really dont know whats wrong, if ya help me out.

    Is the switch on the back of the tach set for 4 cylinder?
