Does anyone here actually know what the two vacuum lines going to the pressure-side fitting of the power steering pump on 4th gen 4Runners do? I've heard conflicting stories. Some people say its for bumping the idle when turning the wheel at slow speed, others say its the control mechanism for variable-assist. Anyone know for sure?
I've looked at the service manual and its rather vague about it all.
