G35TT with Ultimate n Greddy harness wont start
I need help on this big time guys. I have just completed the Greddy TT install on my 03 coupe I didn't want to run the E-management blue so brought an Ultimate and the N13 plug n play harness for the VQ so I don't have to cut into my harness. Now this is were the problem starts.
I plugged in the Greddy harness between the ECU and the Car harness and then into the Ultimate. When I try to start the car it doesn't start up. I have all jumpers set correctly ign set to 12v and have tried it on 5v.
Now when I remove the Ultimate from the equation and try again.. the car still doesn't want to start. So it has to be the harness I think... can someone confirm this?
So when I remove the harness and plug the ECU back to the factory harness the car starts up with no resistance at all. So even tho its suppose to be plug and play... am I suppose to wire something else up? is there a small detail im missing?
Its late but i'll take some picks of the harness and how I have it installed tomorrow and post pics... any help would be great guys. Im really feed up on how bad the information is that came with this unit yet I see how good it can be. There is also no good sources for information about installing problems available either. I really want to get this glitch fixed so I can get a decent tune going so I can feel what this kit has done to my car.

I can't answer your not start question, sorry. But I advise you to throw away your greddy e-manage system 
It's going to do you no good, and its a proven fact. But good luck.

Did you happen to buy this unit used? Is it an older model?
I had this issue with mine at the very beginning. I ended up calling several shops and finally speaking broken engrish to someone over at GReddy. I can't promise this is the same issue, but mine had to do with the injector ground. Check it all the way through and be sure everything looks right. There was also an issue with the diagrams... and now I can't remember where the error was (it was only on the very early prints/models - hence the 1st questions).
