A4ld question

I´ve bought a 90 A4LD out of a 2,9 12V. This tranny has a 3-4 shift solenoid. My car is a 87 TC, there was an A4LD inserted, but this Tranny has has only a look up solonoid and no 3-4 shift solenoid. I´ve seen a Cable which has no connection. I suppose that this tranny there in it was not the original. The A4LD with look up has a connector with 2 cable, the A4LD with look up and 3-4 shift has a connector with 3 cable. My A4LD wirig assy(the original from the TC) for the tranny has got 3 cable for the two solenoids.
My question
Can anyone tell me, which cable is for the look up solenoid and which is for the 3-4 shift solenoid? Does the 87 EEC can do that generally?
