On the throttle bodies you have three plugs/rubber caps
and you have 3 hoses all the same length that plugs into a 3-4 fitting( a plastic vac connector that has four connections) then the fourth one goes from tee to the map sensor i would say on throttle bodies that it does not matter witch vac hose goes where
on the coils you should check for the ignition 12 volts i think on the outer blade terminal if you have 12 on one of them then the other two should be fine because they are linked together
any small code reader should read codes but get the tuneecu like
@atomsplitter said you will be glad you did
