Default Re: 1998 sc2 tach issues still

Ok so on my tach adapter "per autometer" I connected the red/ green wire to the ignition module side .. Then the red wire to the pcm side of the brown/ white wire then I got no signal at all at tach ... Brown/white wire is cyl 4 signal output .. With adapter tach didnt work ... Without adapter I got 1/4 signal ... The white wire at the module I got half the signal on tach .. Havent tried the adapter on that wire yet ... But I'm not optimistic on that wire either ... Grrrrrrrr
