The first is def a ground so just find a nice clean spot near the fuse box to ground it, the second photo does go to the ignitor but i'm not sure what you are asking. The third I can't recall and cant look as I just had surgery.

Usually the 1jz has a noise filter on the igniter. Yes it goes to ground.


Second I don't get what your saying.

ok i got the first right, the 2nd and 3rd photos are the same plug. on of the wires and the front of the plug. there is a black, black w/red spotted, white/blk stripe (which the blk, blk w/red spotted and white w/blk stripe go to gounds) and the last is red w/blue stripe. i looked on the diagram and only red W/blue stripe is going to the Idle air control valve, which has its own wire from ecu plug to IACV so why is this other wire needed?
