i just traded my honda crx for an 86 n/a rx7 that does not run and supposedly needs new coils i havent looked into it much. i do know the coils are not getting spark but thats another thread. the thing im wanted to know is i have a few connectors that are unplugged and i was just wondering what they goto
here are some pictures of the connectors.
here is a picture of the coil there are three plugs with nothing going to them 2 green and one black

here is another picture of an unplugged connector by the washer fluid bottle

 

All of the harnesses had every option built in, so you will find plugs that don't have stuff plugged in and its nothing to worry about.

I am not sure what all those plugs are, but they are not important.

 

The green ones are test connectors. They don't plug into anything.

I don't recognize the black one, but you can check around to see if there's a male plug for it.

The white one is for the cruise control? I can't see enough.

 

Top pic, the 4 prong connector is for the coil, iirc. Bottom pic, assuming that tank is mounted on the firewall, it's the sub-zero assist reservoir. That's filled with 90% antifreeze/10% water. It's designed to squirt that mixture into the combustion chamber to prevent icing during cold starts on very cold days. Mazda issued a TSB years ago to remove them and CA cars never had them due to CARB rules.
