Yup. use a ground wire between truck and trailer. don’t rely on a hitch ball as a ground. I’m not familiar with a 95 , but does it have separate rear blinkers and brake lights? You may need a 7 wire to 4 wire adapter box. Any RV place shoud have one and they are not that expencive.

Amen. I had a snowmobile trailer whose lights didn’t work. I finally quit screwing around and wired a ground wire directly to each light from the white wire in the truck harness. No problems after that. Most of the better quality utility trailers these days are going to this direct ground setup rather than trying to ground through the vehicle frames.

I have purchased a horse trailer in May 99 and wired it to a 1988 GMC truck, no problem. I recently purchased a 1995 chevy silverado which has a factory installed harnes but no connector so I bought a six point connector and wired it according to GMs instructions re: color wire etc. When no running lights are on or brakes applied, the directionals and backup lights work fine. If running lights are on, or brakes applied, all the marker lights, running lights and BACKUP LIGHTS are illuminated DIMLY. The directionals and backup lights no longer work correctly when brakes are applied or running lights are on. Took the truck to a new trailer and plugged it in to make sure it wasn’t my trailer. It wasn’t. there seems to be some cross of the backup light circuit and running lights. If the backup light circuit is disconnected, the running lights will not come on at all. Is anyone aware of any generic problems re: late model Chevy or GMC trucks and how to correct the wiring? Would appreciate any insights you may have on the subject. Jeff Brewer
