Engine swap Cg10 to cga3 JDM

Hello to all
My car is a Nissan March 1998 facelift 1.0 manual

As you can see on the pic the new engine it looks like cga3 and not cg13 (not sure if is cga3) how can i know the model of the engine ?

Besides this the problem is

I just start my engine conversion from 1.0 - to 1.3 (1.3 was from auto car)
The 1.3 comes with the Ecu from another engine 1.3 that also has one plug in the throttle as mine

The problem that my mechanic found is that the 1.3 engine in the throttle body has 2 plugs and mine has only one plug please check pics. And said to me is going to be big problem with the throttle and the ecu readings


What we can do ?
Any suggestions ?

Please help meeeee

The JDM CGA3 still runs on a traditional distributor based ignition system, which is a good thing and makes it much simpler.

I believe the JDM CGA3 inlet manifold is the same as the CG10, so you'll be able to fit your original throttlebody from your CG10 onto the CGA3 without having to worry about the TPS wiring.
 
Dear Low Rider Thank you for your answer
We think to change only the throttle position sensor and check if it works. maybe we are lucky.
In Uk the 1.3 and 1.0 throttle body are the same ?

Yes, swapping the throttle position sensor will also work, as long as it's set in the correct position (calibrated). The 1.0 and 1.3 have the same throttle body, sensors and fuel injectors.
 
Good morning !

CGA3 has different alternator harness (same wires but different connectors)
has a different distributer harness (my cg1.0 has 7 wires and the cga3 has 6 wires different connectors also )
has a different Throttle body harness ( Mine 1 connector and the cga3 2 connectors i will put mine to check it )
Also a had to check if my new engine has a knock sensor (another problem in the list )

I don't want to send back the engine and get the CG1.3 because the engine is at VERY GOOD condition is like New !
The mechanic said to me that the engine has maximun 15.000 km !!

Anyone knows something to help me ?
