Extra Harness Plug Behind Gauge Cluster

I recently swapped my cluster and the new one used the same 4 plugs but I noticed a 5th plug tucked up behind the cluster and taped out of the way. Anyone know what this plug is? Its one of the wider plugs. (40 pin im guessing)

 

Got a picture of where this is located kind of like a general picture of where you talking about and a picture as you get closer?

 

Directly behind the cluster, taped to the harness that supplies the other 4 plugs to the cluster. If you were to un-tape it you could plug it into a cluster if there was a 5th hole. My dash is already put back together otherwise I would take a pic of it. Its in a 96 Gen 1

 

No one?

 

hmmmm..when i had my dash tore apart..don't remember seeing this..

could be future wiring for e locker lights and/or Auto Tranny lights..

about all i can think it would be..

 

My truck is 2wd so I was thinking it may be the plug for 4wd lights as well

 

Ahhhh yes that would be it. The 5 Luger gauge cluster is different.
