After swapping the engine in my Blazer, I am left with some things that don't go anywhere. I don't think they went anywhere to begin with, but am not sure. Can anyone tell me what these things are for and if I need to hook them to something???
1st and 2nd pictures are of a three prong plug (edge is burned away so you don't really see the third slot)/receptacle. I'm pretty sure it wasn't hooked up when I bought the truck and someone said they thought it was for a 700r4 which the truck no longer has (T350).
In the second picture there is another plug (above and to the left of receptacle plug) that I also don't think was hooked up to begin with?
3rd pict is a plug with four fittings(?) and it has a lot of green on it. I'm not sure if it was hooked up or not?
4th pict is a plug above the distributor cap that is the same situation as above.

The third one looks like it might be for an ESC distributor? I can't remember if mine had the weather pack connector, or whatever it is called.

The truck does have a ESC badge on the back, but I think that stuff is long gone. So I guess I don't need to worry about that one?

Yup, that is the plug for the ECS on the dizzy. If it does not have it anymore, no worries then.

4th looks like the plug for the a/c

that explains the extra plugs for my 85! I think I had ESC (not anymore) the a/c plug is just hanging there, and the plug for the oil pressure sending unit (mechanical gauge).
