N3 Detroit series 60 Injectors on DDEC 4

I think I would do the the wiring at the dec5 injector connector using the dec4 wiring harness.

 

I was doing some research to see but it is that time to go fire up the machine. There was someone else who posted something on a similar topic going from ddec 4 to ddec5.( was swapping engines in truck) I hope it works out for you.

 

The DDEC4 engine is a completely different animal then a DDEC5 engine as is all the wiring, ECM's & the ECM programming. The wriring isn't "conversion" compatible. My suggestion is IF you really want a DDEC4 engine, buy a truck w/a DDEC4 engine h be happy.

 

So take this as vague advise. My experience stops at Ddec4. Ddec5 I have minimal experience. #5 head has one less intake bolt hole. What cam profile works with N3 inj. And #4 ecm. What tone wheel works on #5 cam with #4 ecm. I dont know all these answers. Maybe someone will. But I would be asking them. I'm all for using what you have, thinking outside the box. But I feel your asking for more issues than gain. If your not going racing, ecm, cam, injectors your gonna wanna match.

I'm willing to bet it would never work. I wouldn't even try it. Everything about a ddec5 is different then a ddec4. It's not even the electronic side of things, but injector hights and injector lobe profiles ect ect . If you want a ddec4 get a ddec4. Frankenstein engines rarely work out.
