final stages 2jz-gte swap. What color wires go to the map sensor, Gide to link if available.

 

I think the best way to do it is trace it back to your ECU. There are so many application the 2jz could have come from so wire colors are not always identical from one to another. Pictures of the front of your ecu will be a good start.

 

I have the 2jzgte aristo ecu.

 

More than likely, you'll have a brown in pin 1, a green in pin 2 and a yellow in pin 3

 

green is usually the signal, goes in the middle spot, I have also seen this as red.
brown is usually for ground, sometimes they use yellow.
the power wire is most commonly blue/red.

maybe you could start by telling us the wire colors you have?

 

Traced the map sensor wires and connected them to the ecu and now the car won't start put everything back together to how it was and it don't start I lost all power and fuel.
Have to check the harness again and make sure nothing got loose or disconnect.

 

If indeed you have the Aristo, you must have the 4 row pin. From the information I have gather, it seem as it goes this way. Correct me if I am wrong.

Face the connector plug so that you are looking straight at the pins. The push to unlock/release is upward.

Pin 1 (left)- should trace back to E02 ground ecu pin 79. This is usually just a ground that is grounded with the engine, not the chassis.
Pin 2 (middle)- should trace back to PIM ecu pin 62. This output variable signals to ecu.
Pin 3 (right)- should trace back to VCC ecu pin 41. This provides constant 5v to MAP and TPS when engine is on.

My suggestion is to use a digital multi-meter. Follow the instruction to be sure you don't burn your ecu up.

Find VCC:
1. Select volts.
2. Switch ignition to on, but do not start it up.
3. Unplug MAP sensor.
4. Red prob to one of the ends. Black prob to ground.
5. Which ever register 5v, thats your VCC ecu pin 41

Find Ground (wire color should be brown):
1. Select continuity
2. Red to one of the ends. Black to ground. If it reads 0 than its your ground. Some multimeter has a sound when its infinite.
Typically the color brown is the ground.


Middle for sure is PIM (Pressure Intake Manifold)

Thanks.
For some reason i lost power to the ecu.
