Power steering question

[mikeroy420]

There is a sensor in one of the power steering lines. Do I need this?

it is to compensate for load when you turn the wheel at idle i don't have it in mine but i also don't use an IAC since i am running a standalone and i cannot figure out how to wire it in

my wires broke,thats why I'm asking

You can leave it disconnected with no problem. BUT idle will drop somewhat when turning the wheels at idle.
