I have completed my 4th gen dash swap and the tach is acting weird now. It jumps around and when I give it gas it goes up way to fast to like 6 grand. it shows me cruising around in 6th gear at 4000RPMs the tach is gotta be the simplist gauge to hook up and its not right here. My old tach was fine. There is 2 white wires going to cluster and 1 white on the 4th gen cluster. I tried one white one and got nothing and the other works. what can cause this? also the speedo is working but it wont go past 30mph and I still get a VSS code 24. I have the SGI5 box and the cluster wire for speedo is hooked to OUT3. I use to have one of the wires from the t5 connetor plugged into there. where does it go now
