Aftermarket Trailer Light Harness

Hey all. So when I got my WJ I knew it already had an aftermarket trailer light harness in it. I have never had to try and use it until recently. Come to find out, the thing didn't work. Started checking into it and found a couple of things. First, the module was bad so there's that. Also, it seems to me that the 12V wire is in the wrong place. From what I could find with the meter the thing wasn't even getting voltage. In the picture I have marked where the pin is currently with a red arrow and where it should be from what I can find with a yellow arrow. So I ordered a new one, since the module is bad, and it is pinned out the exact same. I haven't been able to find anything in my looking into it. Is my WJ just wired up wrong into the factory plug or is it different in an 04 versus other years?

I just saw this. Thank you for the picture. That did indeed confirm my suspicions. 2004 is different than previous years. I really appreciate you putting this to rest for me!
