Hallow!
I've found some "free" connectors in my V740 (B230F).
I've took some photo about connectors in my car. So,..In photos I've marked
this connectors by number 1, 2 ,3 and 4. So If
You can answer for my question: for what I can use the 1, 2, 3 and 4
connector??

The right side of engine - near coolant bottle:

The left side of the engine - near air filter box:
http://tiny.pl/gdg2
http://tiny.pl/gdg8

And next "free" connectors - near left head lamp (between left head lamp and
air filter), here are the photos:

That is a test point. Normally nothing should be connected there

Sorry don't recognize this one.

This one is for the rear washer pump. Sedans and Wagons use the same
engine harness, this one is not used on the sedans.

gdg1/gdg4:
r/w wire grounds the constant idle motor (IAC) to cause it to go all the
way shut so that you can set the base idle at 750 rpm.
The g/w wire reads the output voltage sweep for the 02 sensor feedback
from the control unit for setting idle CO. For LH cars the output
voltage sweep centered around 2.0 voltsDC with a clean and accurate MAF
sensor. The adjustment range ran from 0.01v-3.7v A good sweep would be
1.7-2.7v or so.


gdg2/gdg8:
The pink wire connects to the starter solenoid. You connect your remote
starter switch B+ there to spin the motor for adjusting valves, checking
compression, spinning belts on and off, or for whatever reason you need
to turn the motor effortlessly.
The Y/R wire is the test point for the EZK control unit. It will
generate a flash code of 1-4, IIRC, through a test LED. If you make one
with long enough leads to reach through the back of the hood opening so
that it can be positioned under a wiper you can observe control unit
detected faults while test driving the car. There is only volatile
memory in the control unit so that once the key is cycled off the
recorded fauts are lost.

So I've to connect it with the ground (-) ??

So,..If I want to move he starter, i've to connect the pink wire to the + ??
From acu??

OK,..have You got some instructions how can I test the EZK?? What LED I've
to use and how read the flashes and some table with meaning on flashes. You
are sure that is the test point for EZK not for ECU?? What I can test by
this?...all ignition system? Bad reading from Hall sensor, ignition coil ,
etc.???
