okay... if someone have a 2000 and up neon and they have put a tach int here.....can you tell me where the tach wire is?????i dont see no grey and light blue stripe wire........2000 and up neons have only 1 harrness going to the cluster not 2 like 1999 and down neons...

I put a tach in my 2000 awhile back...there's a group of wires going to the coilpack, there should be a gray one in there. If I remember correctly, it was either gray with a blue stripe or blue with a gray stripe. Anyways, it gives a reading but I still have to get a tach adapter because it only revs to 1500 when I'm cruisin on the freeway at 70. I'll re-post when I check the wires again tomorrow.

its a grey with light blue strip found either by the wiring harness to the fuse box or the coil
