After every wire from my car is connected to the 1jz harness, there are like 8 wires left and have no idea where they go. It's the wires from the wide WHITE connector.
Tell me more and I may be able to help. Is your computer a five plug or four plug unit. Is the white plug on the end of the wires to plug into the car somewhere. If so - how many wires on the plug. I traced all the wire before we pulled out our 1JZ from a JZA70 so have a list of all wires.
