Unless you can track down a wire harness to mate the connector from your car to the new ecu pins, your going to have to repin the connectors on the new ecu with the wires in your car.

If you havent repinned a connector before, its pretty simple one you get the hang of it. I use a paper clip, but there is a special repinning tool that can be purchased for a few bucks- harborfreight probably has it.

ok ive decided to say screw the ECU and swap the intakes out to make the engine a dpfi for the time being...im still working it out but i think it will allow me to use my old wiring harness and all woot woot BTW anywhere i can look for a good priced upgrade for a crankshaft the shaft in this one is shot...it spun the harmonic balancer LoL so im thinkin of trying to do some upgrades while i have it torn down...id love to hear about some cheap paths i can take...anything under 100 bucks..
