Swap is almost done in my 1988 2500 4x4 pickup. Got a few questions about some odds and ends.


What does this connect to? Its the outlet/inlet on the throttle body?
EDIT/UPDATE: This goes to the valve cover vent, but apparently not the pcv?



What does this connect to?
EDIT/update: This goes to the rad i think, or to a coolant line, but because im doing the tb bypass mod, i dont need this.


I know these goto the tranny and are VSS, but what does each individual connector do? There are two that are the same, made out of blue and white plastic? The pinout says stuff like VSS and 'tranny connector' But what sensor specificlly do they goto?




Vacuum hoses? Where to?




And what is this outlet/inlet about?On the water pump, i know the other two goto the heater core, but where does this one goto?
EDIT/update: This can be plugged, apparently it goes to the oil cooler.

 

No one knows where any of these go? or are for? GImme a hand, im almost done the swap! lol. Thanks.

 

Well the 3rd outlet on the water pump just gets plugged as its for sending coolant to the oil cooler, AFAIK. But everything else i still need a hand with. Can i just plug the small vacuum hoses. I cant find any pics on the net that show where this stuff goes. Thanks!
