Please help identify this plug!?!?!?
 

My 2006 f150 fx4 truck was recently stolen and they did a bunch of electrical damage to it disabling it from being driven. I've fixed almost all of it except this plug. I don't know what it goes to. Im pretty sure whatever it went to was removed because there are 2 bolts sticking from the firewall where something was mounted. The plug is wired into a small speaker/siren as u can see. Please tell what you think it supposed to plug into. It's up on the driver side under dash right above the emergency brake.

I'm thinking the speaker is the key chime, but that would only need a couple wires, not that whole harness. Regardless, I'm thinking the other end should plug into the ignition switch so the chime can read when the key is in. Sorry your truck was stolen. That sucks.

Here's more pix of the plug.

I thought that same thing but the wires aren't long enough to reach up into the steering colomn. Does anyone have a diagram of all the under dash wiring and plugs and where they go??

You can get all the wiring diagrams you need from http://www.motorcraftservice.com/vdi...bs&gutsid=pubs same literature dealer tech's use.

Did insurance not pay to have the vehicle fully repaired?

It goes to a small black box, 3x3 inches. I have no idea what it is though, sorry.

Does anyone know what that 3"x3" black box is?? It's missing from my truck and I think/hope that's what is causing it to not run.

Let me take it off this morning and see if i get a part #.
