I have a 98 ford taurus sho 3.0 4 valve with a bad motor, I have a 3.0 2v motor out of a 96 taurus, can anyone tell me if the wiring harness would have to be replaced too, I have put the motor and pcm out of the 96 in, but the motor will not run , any help would be great , thanks

If you have a '98 SHO it would have a 3.4 V8 not a Duratec V6.
