Dezod AEM V2 to AEM Infinity 6 Conversion IS300 02-05 Auto
*****Warning, is your responsibility to verify your connections, I'm not responsible if your car gets on fire, you loose your job because the car took more time than expected, you have a piston knocking the hood asking letting it go out or a thermonuclear war starts. Verify all before adding power to Infinity, any doubt ask first!!
Using the harness that was build by Dezod, I replaced the 4 connectors with the one for Infinity.
I did first a patch harness to use both EMS in the same car for testing, I don't wanted to stop the car.

Infinity uses an external relay, here how to connect it:
Legend: Pin of relay > Pin Infinity or as described
Pin 85 > C1-47
Pin 86 > +12V from Battery with fuse
Pin 87 > C1-63 and C1-68
Pin 30 > +12V from Battery with fuse
With this and the Base Cal you should start your engine with no problems, go to the wizard select your injectors and your map sensor.
Iím adding some new functions to my car, when completed I will update the thread.
For the VSS Vehicle Speed Sensor you should read here:
Any questions I will help the best I can. I'm not a tuner but the Infinity is so powerful that with its integrated live log I tuned my car myself.
PS: I will look for Pins numbers from OEM ECU and add it so you can build your own harness.
