I have an 03 Evo and was curious as to if I am able to use any engine harness from 03-05 to replace my current harness. I am sure it will work but I know there were a couple change under the hood at that time and wanted to be absolutely sure before I replace my existing harness.

My coil plug has been cut off and lots of clips on the harness are getting nasty/broken/worn etc.

 

As long as its not a mivec harnesses you shouldn't have a problem.

 

So you have a 03 and want to know if you can use a "03"-05 harness.................im gonna go with yes.

 

I agree

 

I just wanted to be sure any evo 8 harness would work on the first year. Thank for the input.
