I was doing some work on my 86 Accord LX (AT) today and I needed to remove
the battery.  I found that two barrel shapped electrical plugs directly
behind the battery were disconnected and probably have been so for at least
a few years, i.e since one of the previous times a "professional" mechanic
worked on the car.  One plug has a red/white wire and a white wire and it
plugs into a blue socket.  The other plug has black and white wires and it
plugs into a black socket directly below the blue socket.  Both sockets are
mounted on a post adjacent to the fuse box.

I'm wondering what issues having these plugs disconnected may have caused
and what differences I might expect once I get the car put back together
(need exhaust parts) with the plugs connected.
