The name of the mfgr is part of the picture. Item itself is probably made off shore. Old school North America holds to the convention that red is positive or "hot" and black is ground but be careful here. The cars we use and work with also use the negative ground convention as in positive or hot/red goes to the positive side of the battery and black/negative goes to the negative side. This was not always the case. As late as the fifties, prior to 12v batteries becoming common, certain mfgrs still offered cars fitted with positive grounds, not negatives. Although much older than that, my buddies' Model A is still a great example. On it the positive cable from the battery gets attached to the frame and the negative cable from the battery goes to the starter stud. Which is better has been an ongoing bench racing subject for decades, but those who do switch to the negative ground typically report easier starting and fewer wiring problems.
I mention all this simply because red, although most common, is not the exclusive color for a positive wire. In my late model truck, I've found black is usually the ground but discovered that positive can be red but can also be orange.
As for the colors of the wires, I am on board with the notion that red for positive and black for negative as the default or common colors to be used does make fabricating a wiring harness substantially simpler. However what we prefer is not necessarily a global convention and other nations might be used to different combinations or just don't give a FRA how it is done over here. Also what we accept as convention is exclusive to the automotive genre. Ask an electrician, any electrician, what is hot and what is not and the colors will be totally different. Any electricians on the site who might care to comment further?

Oh, yeah, if I did acquire a socket wired according to the picture, it is an easy matter to slip the spade female ends out of their pockets and move them to end up with a more common and friendlier configuration.
If'n anyone needs a 4-wire connector to replace that melty one under there....

I have used those but I just use the housing, I don't use the cheap wire and connectors you get with those. All my eletrical connectors are Gates
My current fix is using weather packs with correct size terminals running a three port for the light wires & a single tied into a 30 amp fuse (will be either a weather proof ATO or Maxi if I get things figured out on my fusible link to Maxi conversion figured out) to add what GM left out. A suggestion to everyone is to put a 30 amp fuse in a weather proof holder to help prevent future melt downs.
The lead can be shortened from going all the way to the starter, and connecting to the battery or alternator, too.
Yep. They run all the time. Do a search here, and you find multiple people concerned about the same nothing.
