I also pulled and replaced J14 and no results. test light J14 fuse and there is no power to either side of box. not sure where to go next? Is there a relay for J14?

Have you double-checked whatever wiring you did on the plug? The general rule of thumb....if everything was working normal, you did some work, and now it doesn't work......the highest probability is the issue is from the work you just did. Have you probed the actual wires going into the plug, or just going off the trailer not having any power? Also check the ground. From my experience ground issues are the most common problem when it comes to trailer electrical.

I have unpluged the tow vehicle put no power at the truck. Thats why I went into the fuse box thinking I blow somthing

Question: Did it work before you touched / made changes to it?

Just trying to get a better understanding of the specifics so we can point you in the right direction.
How did you check for power? A test light touching the terminals of the truck side trailer plug maybe?
Did you probe/check the wires going into back of the truck side plug? Or just the output terminals?
Did you actually probe the fuses to see if there is power at them, or just visually look at the fuses to see if they were blown?
Did you have power to the trailer prior to doing the work?
Have you verified the ground going to the trailer? Are you providing ground through the plug or just relying on it being hitched up and grounding through the trailer ball?
