crazyrx-9

so, i got everything in, and there was two doubts i had, 1. the knocking wire on the ecu wasn't white like my rx-7 repair manual told me, and 2. i noticed when i was connecting the aif flow wire that on the harness the air wire and a black wire diagonaly from it were linked together a little further down the harness...?, it that how it is on every car?, and can someone go through the initializing steps for me, primarily the throttle angle one, i didn't really understand that step in the instructions... thank you much .. and my name shouldn't be crazyrx-9, its zoomnrx7 if i reply later on in the thread.
