If you are good in wiring up the car then get yourself a helms manual and then connect each wire.. Let me tell you first, wiring up a 94 gsr to a 89 isnt a easy job. Its very hard and time consuming. If you cant wire, then I would sugges you take your car to a good shop and have them wire it up for you. If place racing is back up, and you cant wire for ****, then maybe you should think about get a standalone. Such as haltech or speedpro, dfi etc. If you go with a standalone such as the one i jsut mentioned then you wont use the factory harness. Believe me its a pain to wire up b18c to a 89civic. And you using a cable tranny right? or did you convert your shell to hydro? its going to take time.
