dude i have the same car and put in a reactive tach, go under the hood right in front of the driver, along the left side of the car less than halfway down from windshield to front bumper, there is a little random wire with like a green cap on it. it is right on top, i even think it is mounted. it is a wire used to test your idle or somethiing like that. i just spliced my tach into that. just run the wire through your firewall. there is a little rubber plug you need to punch out and drill a hole in if you want to keep it and then run the wire through it. hope this helps.
