What wire for an aftermarket Tach?

I want to connect a aftermarket tach.... i'm getting it for free.... what wire do i have to connect it to? What color is it?

here's a site that you can go and see
http://hp.autometer.com/instruction_download/tachometers.html

8 CYL. - No adjustment is necessary.
6 CYL. - Clip BROWN wire loop only.
4 CYL. - Clip BROWN and ORANGE wire loops, Insulate with electrical tape.

is this universal wire color on all cars? I have a 00 rolla

You need to tap into the tach wire that goes to the computer? It's black, I don't recall exactly where it is but I can find it if you like, email or pm me.

the computer is right behind the cd deck?

It's underneath it, in the center console.

I taped mine to a lead behind the cluster...I forget which one.

It's either coming loose now, or my tach is broken..dunno which.

i got mine installed, it was the solid black wire. The light and negative i attached to my cd deck power.... i was too lazy to do it another way

Is it always lit now?

I tapped the light wire into my taillight fuse, so it's not lit unless my lights are on.

no its only on when i turn my lights on

The tach wire is on the C connector of the ECU, pin 8, and goes to a black connector near the ECU.

Would that be the same if you were trying to wire up a stock cluster w/ tach?

Yeap
