Ok ihave the 5in sport comp tach and the quick light from auto meter...the tach i got to work fine but have no clue where to start with the shift light...

how there is a plug on the back of the shift light...however i have nothing to plug it into..so im guessing i need to order that other part from auto meter...OR is there i way around it? and when if i do need the other plug where does it go from there?
any help would be great since i cant get auto meters site to download anything about this...

thanks guys
Matt
