I have a question on how to hook up a tachometer to my car, i have a diagram of my car from this site but, the wire tht is supposed to be loose for the tach is in a jacket with the rest. That all goes to the PCM, am i to just cut that wire pull the wire out of the plug. I can't pull it out of the jacket, its in there pretty good.

I dunno, but is it one of those big ones with the shift light...

For your sake I hope not

1st, your from Sebewaing.

2nd, you dont need a tach unless your doing serious mods.

3rd, are you doing serious mods?

4th, if so, I will tell you what to do. Otherwise, nope.

lets see
it isn't a shift light one
whats wrong with Sebewaing?
i've put flowmaster on my car, dual outlet 2 1/4
NGK Iridium Spark plugs
K&N Air filter and oil filter
I just want my car to have a tachometer since it didn't come stock

SO yes, i'm into serious mods

Are you talking about the white wire that goes to the ICM? You don't want to cut that, it's supposed to be hooked up. Just use a tap to splice into the line and connect your tach to that.

Enough of the sarchastic comments
