hey guys, so lately my door lock fuse keeps blowing and im thinking i have a short.

But then i notice that i have a plug hanging in the door, so my question is where does the small plug connected to the master control harness go?? I have the two hooked up to the master switch but where does this third on go???

if anyone could check real quickly id greatly appreciate it, im having a bad day. my 97 grill just fell out and got ran over. there goes a bill
