I am pasting info from other forum and it will be of great help to some ppl who love to trace ECM wires and its diagnotic.
This info is with respect to terminal arrangement of ECM (PCM) coupler when viewed from harness side looking at computer.
There are three connectors / looms connecting to the ECM each of which is a different size so you can't mix them up.
The left-hand one has 26 wires and is referred to as connector A with pins A1 through to A26.
A1 is at the top left going along the top row to A13 then to the bottom row directly below A1 is A14 then along the bottom row to A26.
The next two connectors follow this same logic.
B1 through to B16 on the second (Middle) connector.
B1 is at the top left going along the top row to B8 then to the bottom row directly below B1 is B9 then along the bottom row to B16.
C1 to C22 on the last (Right hand) connector.
C1 is at the top left going along the top row to C11 then to the bottom row directly below C1 is C12 then along the bottom row to C22.
I trust that makes sense!!!
Now to explain the function of each connection.
I have included the colour of the first few wires on each connector so you can tell you have the orientation correct.

Now to the specifics of Boskos question...
Hook the signal wire of your fuel mixture display to C19 which is a white wire.
For a kill switch you can use the fuel pump relay output at B2... just cut this wire and install a switch.
PLEASE READ!!!
Be sure to disconnect your car battery before removing connectors from the computer.
Be sure to disconnect connectors from the ECM before adding to or altering the ECM wiring.
Never install a voltmeter or Ohmmeter into the ECM connector’s terminals when the ECM is installed. (Disconnect ECM first)
Never touch inputs / contacts of the ECM with your fingers.
Basically I am trying to say the computer / ECM is a very sensitive and expensive item... If you are not sure about it don't touch... they are susceptible to ESD electro static discharge.

Pls keep in mind this DOES NOT apply to euro III balenos.
new car has M16 series engine.

do we have stepper motor or vacum/solenoid ?
Hey karthik dude .. what say.. ? is this applicable to Indian ECU ?
Chetan , if you observe carefully all the points highlighted by you are off the 1.8L baleno engine sold abroad not in India .. So none of it holds good for our Indian version ..
Chetan, Euro 3s have heated 02s... Not sure abt egr or evap actuators, will chk on that.... And its not applicable to indian systems at least as a direct fit, but shd be possible with a little work.
Hello everyone, i am new here..
i have baleno ECM which have serial number 33920 60GB 1. made by Denso
it have 3 jack, 2 yellow and 1 grey.. do ECM wires up there is same with this ECM ?
or do you have other ?
thx
@wimasy, the first post by ECM is compatible with your ecu.
Looks like the wiring diagram needs couple of small changes..
B7 = Injector 1
B8 = Injector 3
B15 = Injector 2
B16 = Inector 4
@rdkarthik, thanks a lot.
do you have any technical document or other resource for this ECM ?
i will implant this ECU on my Suzuki Vitara G16 engine, the old ECM work with banking injection (2 injector on same time).
from your posting, i'm sure i will have great improvement, this ECM can use dual ignition coil.

I dont have any technical documents for that ECM.
Why are you planning to put this on to your vitara? If the vitara was using semi-sequential/banked injection, i am pretty sure your sensors would not be compatible with the baleno ECM.
Does your vitara have a distributor setup? What about crank/cam sensors?
Also note other ECMs may fit connectors on your car, but may have totally dfferent pin configurations...
@rdkarthik
yes, you're right, my G16A work on semi sequential, but i already install new sensor from newer version of G16A, which work on fully sequential injection.
i have crank position sensor, and my engine is already modified for distributorless system.

all the best for your project :) ..... just be extra careful with wiring and pin configurations.... let us know if you need any help..
after tracing pin out one by one and open ECU casing, i found that previous posting isn't compatible with ECU Denso 33920 - 60GB1. Here is right one.
