"Free" connectors in V740 ?

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

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.

gdgs/gdg6: What Mike said.

Can You write some about it??

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.???
