I did connect directly to the fan motor, pass the wire through the firewall

But It's not running 100% of the time, by time to time, it stop. Specially when I' idleing witch make sens in accordance to the same repair guide :

Here is the testing procedure
"1. CHECK COOLING FAN SYSTEM
(a) Put the vehicle in the following conditions :
(1) The ignition switch is off.
(2) The coolant temperature is less than 95°C (203°F).
(3) The battery voltage is between 11 and 14 V .
(4) The A/C s witch is off.
(b) Connect the pickup of ac lamp-on ammeter over one of the two wires for the cooling fan motor.
(c) Turn the ignition switch to ON and wait for approximately 10 seconds . Check that the fan stops .
(d) Start the engine. Check that the fans tops with the engine idling."

And If I do it, it's true that the fan start with the engine and stop after 5-7 sec.
Then start after another 3-5 second stop after another 20
in cycle but not a clear cycle. It start and stop whenever it wants
