Nice diagrams Mugen
Thanks that means a lot coming from someone of your caliber with the ULT.
I started making these when I started having owners come to me with problems because they decided to "TRY" and wire it in instead of getting a pre made harness.
The main "major" error I find is either Vtec is incorrect or even worse they have wired in the ignition point incorrectly because they did not follow the firing order.
I even went so far with the diagrams that IMHO I even show the best place to tag specific wires
AS an example
Tagging the electrical power and electrical ground and the Sensor ground on the PCM side of the harness provides the most consistent electrical potential between the stock PCM and the ULT.
While electrically it does not madder because in "theory" the wires should have no resistance in them and in “theory” be exactly the same point to be the most accurate and as correct as possible I have depicted them as shown.
So does JP17 need to be set to 1-2 or open? I've seen so many threads and it seems like everyone says one or the other. Does anyone have a solid answer?
Hello
I had in my car the greddy e mange ultimate with universal harness but i took a pnp harness for better and after i connect it the car is not start.I hear the fuel pump and the engine is crank but not ignition.When we take off the greddy the car start fine.
Can anyone help me please?
Did it work with the universal harness connected?
What kind of pnp harness are you using now?
The car had tuning before with universal harness and was fine.I buy a greddy pnp harness for better and i take off the universal harness and i put the greddy pnp harness and the car is cranking but not start..
That's good, then you know it's most probably your new pnp harness that is wired incorrectly.
You should check all the wiring but start with the ignition. Think you should be able to find complete wiring diagrams somewhere on this forum if you do some searching.
Here's is one I had saved on my computer

Thank you very much flanders.I had search and find some diagram and my car electrician is say that is correct the harness but the car not start when i put the emu and start when i put it out.
Is there possibility the emu had lost the tuner program?
And i dont know why greddy say that is pnp harness and i had seen in the forum so much problems.
