Poor Wiring by Previous Owner Behind Head Unit

[ClipseAPG]

Hey guys, I've been having head unit/ other electrical issues and when looking behind the head unit after I soldered every connection and heatshrink-wrapped everything as well, I stumbled upon this connection. Now I've heard that factory DSM wiring was bad, but is this original or was it a botched job by the previous owner that may be causing my electrical problems? (In case you've seen my other thread Hard to Start, Car Putters Along, Electrical Power Lost, Gauges Going Crazy as am I, I don't mean those kinds of electrical problems just some specifically related to the Head Unit maybe?)
