You need to know the firing order to know where your wires go.
www.the12volt.com go there, and they have what u need to know.
the wires can only hook up to one place there are two wires but they both go on top of coil but they have different plugs so therefore can only go to one place
Need to know what year 4.3L you have to answer that.
read a manual
Usually the length of the oem wires from the distributor can give you a general idea. Hope this helps
Look at the Drivers side, they should be the same.
that is an undetermined question. i would advise you to go see a doctor for where you think you have lead.
I don't know go check another website
Call a auto part store and ask them the firing order for your vehicle.
Try looking at the other headlight plug
