i just swaped out my stock cx cluster for an ex cluster so I will have a tach. It was easy to install(all plug and play). Well everything works great except for the tach, yes the reason I got the thing in the first place. The prob is the tach will work, but it doesn't show any idle and doesn't even move until about 3k. Also the cruse control light comes on just like the old shift light came on. I put all plugs where they are supposed to be. Does anyone know what could be causing this? Any help would be much appreciated.

P.S. sorry if this is hard to understand, its hard to try and explain. and when the tach does register something its also 3k behind like. Like if it should be on 5k it will be at 1k. I hope this helps someone understand this crazy problem.
