I have a 1992 Lx convertible. I recently changed the heater core and I am in the process of putting the dash back together after the car sat apart for a while. I can't figure what this plug is for. It is a 5 wire plug under the dash on the driver side of the wheel. The wire colors are Brown/Blue, Black /yellow,
Purple/Orange, Grey/Blue and Black. Any help would be greatly appreciated.

It looks to be one of the plugs that go to the heater controls.

It's not for the selector switch. Or heater controls All those switch plugs I have plugged in. This plug is right next to the fuse panel and the wire isn't long enough to go over to the heat control cluster. I was able to plug everything else in and put the dash back in and couldn't find anything. I wound up pulling the whole dash back thinking I missed something but I don't see anything. I am totally baffled. Thanks for you suggestions though.

It's for the Rear Window Defrost Control Relay.
