Need more info....Helllo! I have nss with 6 pins (722.4)
And i swapped transmission another 722.4. But now my nss plug have 6 pins but on tranny there is only 4 pins. The same nss with the same style connector .... What to do?
Transmission code is 201 271 0701You need to specify the full transmission number that the car has, and the transmission number of the replacement.
The 4 wires for the transmission are for the starter and the reverse lights. Not sure what the remaining 2 pins are for for your car. If you provide the transmission numbers in full, it may help.
Ok. Thanks for the help both of youOK.
I am a bit confused whether the old transmission has 4 pins or the new one has 4 pins. But here it goes.
The 4 pins are compatible: pins 1 and 2 are for the reverse light and pins 8 and 9 are for the starter switch. So the car should start and when the gear in reverse, the back up lights should light up.
The extra two pins, 6 and 7 are for gear 2/3 recognition. Meaning, when the gear is in D, the resistance between pins 6 and 7 is very high (open) and then the gear is either 2 or 3, the resistance between those pins is low (short). These pins are connected to the Engine Computer. What the engine computer does with them, I have no idea (yet). So you can put the old nss into the new one.
