i have a 98 S10 with the 2.2L 2wd. i have bought an aftermarket tach and i am wondering on how to wire it up correctly without hurting anything? thanks for your help!

You can get the tach feed from the cluster feed. Tach is pin A3, white wire. Then just wire-up your ground (I use steering column bolts), hot feed from the fuse panel (usually you can plug into a port using a spade connector) and splice into the gray wire for an illumination feed.

For you aftermarket stereo people this should be pretty simple - if you have extra wire behind your stereo - pull out your head unit and splice the 3 power cables into the power cables from the head unit (black to black red to red and yellow to yellow). Now! the hard part right? NO! easy part! don't you dare drill through the fire wall if you have a '98+ truck!!! I have a 1998 S10 5spd no tach in guages. The wires going to the guages HAVE A TACH SIGNAL IN THEM! You will see a blue clip and a grey clip holding in the wires. On the Grey clip side it is the 2nd wire from the left (white-ish wire) cut that wire and hook it up to the tach signal for your new after-market tach!
