You will find an extra wire coming from the plug on your coil. That is for a tach. No rev limiters untill at least the late nineties if at all.

thank-you i think it is a white wire too but is it a wire kind of like the fuel pump test wire? by the fuel pump relay so do i have to splice in to it or can i just connect it to my tach?

It's a white wire with a black stripe. You should splice the wire as this wire also sends a 12v square wave rpm signal to your PCM. Depending on your choice of tachs you may need to hook up a tach signal booster as your tach will use some of the energy required for the rpm signal to your PCM. Tach signal boosters are availiable through MSD.
