Will a 03 wiring harness MT work on 04 ECU
How’s it going fellas!
I recently bought a revup 06 coupe MT with a blown motor but since I don’t want to have the revup, I’m swapping to a regular DE (I know I know) so I’m wondering if I could run 03 wiring harness on an 04 ECU?
I’m also swapping the ignition switch and ECM That’s coming with the new ECU so I shouldn’t have any locking up issues.
Thanks ahead of time!

I think there were two or three versions of the ECM for 2003 and each had a different connector. You may need a different IPDM as well. I'm sure others will chime in, this is a common topic here.
