*SOLVED* Issues with dash and lights. '96 850.
 

Hello all, yesterday I lent my wagon to my wife and it was returned to me with the speedometer, headlights and turn signals not working. However, the hazard lights work and it appears that when I change back to the park lights they come on. I had a look under the dash and found this plug hanging in the footwell:

Here's a better view of the plug:

And it comes from somewhere up here:

I've removed the dash pad and the cluster to get a better look but to no avail. What I would like to know is does anyone know where this mystery plug goes? And if so, how to access it? I'm yet to figure out how to remove the lower dash plastic under the steering column so if anyone could let me know even how that's done it would be a great help.

Thanks in advance.

*UPDATE*; I believe I have sorted the issue. There was a tiny part number on the yellow plug and after some googling it was determined to be an unused accessory plug. After further digging I am thinking the issue is a faulty ignition switch. Hopefully I'll find one and replace it.
