Need wiring help

[2wycked]

Im installing a KA24de in my 93 hatch. It used to have an engine swap but Im just putting a KA back. Anyways on the upper harness there were 2 plugs to connect by the fuse box, a brown and grey. The brown I found but not the grey. Anybody know what color wires go to it?

Also in the second pic I just found these wires all cut off a harness and taped over. Can you tell me what they are or where they go?
