7 pin trailer plug stopped working?

I looked around but didn't see anything relevant, someone hacked the trailer plug to add a 6 pin in the back of the truck, gooseneck setup

Now i am not getting any power to it, well not enough to work right, is there a plug under the hood that i can access to run some tests,

I have already checked the fuses everything is good, now i'm just confused

None of the circuits work? I have a plug in circuit tester that makes it easy to check all the functions. Much easier than using a test light and most RV dealers have them. Also there is a chassis ground on the inside of the frame back towards the fuel tank that comes out of the wiring harness going back to the plug. I would make sure that is still attached.

So i finally had the time early enough not to broil on the concrete, Dropped the spare and got to the ground on the rear harness, took it apart cleaned it up , put it back together!
Not only did it not help but now when i step in the brakes my radio lights dim, LMAO what have i done now!
Wife is at work today so i will pull the ole girl into the garage and run some tests
