Tonight I'm putting my dx motor with mpfi swap into a CRX Si shell. I don't have an si engine harness so can I run the mpfi harness and then just run the 4 injector wires and the 4 distributor wires separately? I'm not sure of the differences in the ECU plugs.

Any help is appreciated ~dave

 

yes/no?

 

Theres an extra plug on the CRX Si that comes out of the firewall that is 6 wires right near the two big plugs that mount on the shock tower. This obviously isn't gona line up with the DX Engine Harness so I need some help. I'm considering taking this hacked up Si harness I have and reviving it with my MPFI Harness.

 

you can't run the DX engine harness with an Si intermediate harness (the harness that comes through the firewall). The plugs won't mate up, and you really don't want to have to re-pin them all.

Just find a used Si engine harness.
