I'm having trouble with the trailer light guys.....They look dimmed, low like there is not enough power....is this ground problem...? I think when I hit the brakes they just die.....I just hate trailer lights.....Any help wherte to look will be great....
Truck is an 04 chevy with the 7 points and the trailer is a triton with the 4 points....I'm using an adaptor.....Should I cut it and just hardwire a 7 point to the trailer...?
Thanks
Nick

I've never had trouble with the adapters, I would about guarantee thats its the ground if not a bad ground connection on the trailer or truck its a problem with one of the ground wires on either the vehicle or the trailer, I just went through this and there was a break somewhere in the ground wire somewhere in the truck harness.It can be a little frustrating tracing it down,but you'll get it.
the white wire is the ground on the trailer ..most ground under the coupler to the frame ..look there or trace the white sounds like your problem is there....dont change to seven plug waste of money for your application .adapter is fine ..truck is factory wiring? what kind of trailer ? lights have 2 or 3 wires on the back ?

Ground
It is a ground problem. Another place to check where I have had problems is on the back side of your 7 pin connector. There is a plug in there where the truck harness plugs into the 7 pin connector itself. The connections commonly corrode there too. Crawl under the truck and unplug and inspect this connection. Clean it all up and apply a good amount of die-electric crease than plug it back in. Good luck.

Well, another thing to check is the adapter. I've found that NOT ALL are configured the same. I had a similar problem that was a "cross-wired" adapter............spent a couple of days trying to figure that one out! 
Also inspect your trailer tail lamp sockets...if corroded, they sometimes cross feed when you apply your brakes & blow the stop lamp fuse (at the truck)...use a buster(jumper) cable to jump from your truck to the trailer & see if that makes a difference...
I always run my own additional ground into the wiring harness of both my truck and trailer because the factory grounds are never protected from the elements where the are attached to the frame. I drill a hole and then fasten the additional ground wire to the frame using a bolt and wire eyelet. After everything is fastened down I then coat everything that is exposed to the elements with bathtub caulk/silicone to ensure that all the road grime and salt cannot cause corrosion between the frame and eyelet Then I splice the addtional ground wire into the factory harness using solder, shrink-wrap and more silicone.
I started doing this after fighting with the factory ground on my '97 Chevy pickup for three winters and have not had a problem in the last four winters since doing the addition.
