Hi this is my second time posting. I know that it’s kind of strange to do an auto swap, but I am going to build the transmission as well. I have a 1994 Honda civic ex with d16z6 motor, with auto transmission and p28 ecm. I am doing a swap with a b16 obd2 motor; the transmission on the swap is an auto. The swap came with a p30-900, which is an ECU for the obd1 vtec DOHC motor with auto transmission. Now the problem is that the b series auto transmission has two connections on it, one for the lock up solenoids; and the other is for the shift control solenoids. I have the connections for the lockup solenoids, but I don't have them for the shift control solenoids on my stock wiring harness. I think I might need a transmission control unit; I can connect the shift control solenoids to my ecu. Does anyone have the correct wiring information? From my under standing if the wires are not connected, the car will not be able to be placed into park. Please help me any one thank you.
