Weirdest trailer wiring issue ever. Need help badly

Ok I have a 97 f350. The trailer is a 35 foot gooseneck. Used a power probe pro to figure out which wire is which. So I hooked them up Into a brand new 7 way trailer plug and hooked it to my truck and everything is jacked up. As soon as I turn the key my rear lights come on and also on the trailer. It's not the running lights or brake lights because they are too dim. My blinkers work. But as soon as I hit the brakes I lose lights on the trailer. This is where it gets wierd. To see if my wiring was wrong I hooked it up to my buddies 06 f150. Everything works perfect!! So then I say well it's my truck. I then go and hook the lights on a 18 foot car hauler. Guess what. Everything works perfect!! What's the deal. Need help badly.



1997 f350 4x4 off road.
353k miles
Stage 1 swamp injectors. TS chip. Leveled on 35" Federal tires and black 18 inch pro comp wheels
3" downpipe into 5" straight pipe 6" tip. (Diamond eye)

1987 Chevy 1ton lifted 24 inches on 53s. Duece and a half transfer case. Mud truck.

The 18 foot car hauler a 7 pin plug? And are you using the same plug for both trailers?

grounds

check your grounds. DC is funny with bad ground. Do not rely on ball metal contact.
Hope you figure it out...
