I think it should be as follows:
Left speaker ground Brown
Right speaker ground Gray.

The cable to the fader in the center console color may vary

Left + is Black/Green or Grey/Brown
Right + is Black/Red or Brown/Red

SOURCE: mercedes 300ce Engine cuts out at any speed, even when ideling.

It sounds like a fuel delivery issue. Mercedes recommends replacing the fuel filter every 60k. If it has been longer than thast since the filter change start there. Fuel pump relays are another common problem on this era. They are located behind the battery. Remove the plastic cover and you will se 2 black relays( yours may have a mass relay if it is a 90 model year, it will have a plastic knob on top that you turn to the left to unsecure it) IT will say kickdown on it the climate control is the other relay and it will say klima. Look for signs of corrosion on the solder pins. If your fuel pump(located at the right rear) is very noisy when it operates I wouild recommend replacing it. During this era of Benz about the only way to diagnose this would be to run a bunch of fuel pressure tests and to drive vehicle with a meter on the relay and on the pump to see if the relay cuts out or the pump cuts out. I always recommend to do both pump and relay because they can cause one another to fail. good luck.

Relay isnt usually the issue. The Klima relay should be on the passenger side behind the battery. Also another relay is under the screwed down cover behind the fuses. Normally the comprssor will not engage due to low pressure or bad pressure switch on the drier. Could also be the speed gage integrated to the compressor. Leak of the freon is normal but f it comes out as fast as it goes or just fast then the evap in the dash is most likely bad.

Crankshaft Positioning Sensor Replacement
Problems with the Crankshaft Position Sensor (CPS) on Mercedes-Benz cars are fairly common. If you have been experiencing stalling or no start conditions, a failed crankshaft position sensor is often the problem. Your CPS may have failed if the engine cranks but it will not start. At first, you may experience no start conditions intermittently. As the crankshaft position sensor fails completely, the car will no longer start or will die when you are driving. Starting problems are initially random, but more frequent when the engine is hot. Other symptoms of a failed crankshaft position sensor are poor acceleration, engine vibrations, poor throttle response, bad fuel economy, hesitation, engine stalls. The engine starts if you let it cool down. If you are stuck on a parking lot and the car will not start, let the car cool down at least 30 minutes and then try again. ( Thanks to MB Medic)

Fuel problems


First start with the basics check fuses relating to fuel and or injectors make sure there is voltage next look into your crank sensor usually if it fails the computer doesn't know you are trying to start the vehicle because the signal the sensor is supposed to give out to the computer is not there due to a faulty sensor once the computer senses the signal from the crank sensor then the computer will send a command to the injectors to start pulsating gas let me know how this turns out for you.

Van runs good then stalls out. then hard to start. If i let it sit for 5 minutes it starts again no problem. Then stalls again shortly there after.


This sounds like a failing camshaft position sensor and weak crank shaft sensor .When crank shaft sensor gets weak it will stop functioning.When crank shaft sensor stops working then ECM will not control fuel system and the fuel will stop flowing. And this can cause the problem.When crank shaft sensor gets heated it will stop working, but when the car shuts off, the sensor gets cold and works for few minutes and sensor again gets hot and it stalls. ---------- Get the crank shaft sensor tested on your Chevrolet venture. ---------- There are many other possibilities for this stalling problem,but crank shaft problem is indicating in your case.

Starting problems


It will likely be the crank sensor, usually fitted next to or behind the bottom engine pulley. A common failure is for the sensor to stop sending a signal when hot, and the engine will stall immediately. After a time, it re-starts but will cut out again when the sensor gets hot again. These sensors are easy to find and replace, and not usually expensive.
