1993 240sx vert- Power window relay

[2LO4URHO]

Right now I'm working on fixing some bullsh*t as wiring the previous owner did that is causing my pwr windows not to work, got a few wires and a relay all melted and sh*t with exposed wiring. Trying to keep my baby from catching on fire. I have posted pics of the relay I need help locating, that sucker is fried cant read the freagin #'s on it, all I know is autozone don't carry it. It's a round black relay that attaches to the side of the breaker box under the dash which if I'm not mistaken is a pwr window relay. Please chime in if you know what I'm talking about. Any cross refference #'s or part #'s where to get it will be very helpfull.

Here's what I'm dealing with:



This is what I believe to be a window relay? Please correct me if I'm wrong but I need to know what it is and where to get it. This looks like the source of the wiring melting.
