There should be a pre wired conector for your truck at advanced auto or local auto parts store. These are simple to install and consist of unpluging a connector on the bottom of your truck and connecting to the pre wired harness.

Trailer wiring

Trailer wiring uses the fuses for the car lights. Turn signal, running ans brake lights. Some plugs also charge the trailer battery if so wired. Check the ground wire for a good body connection. This wire often gets overlooked and can stop all trailer lights if it fails.

When I tow with my car the left blinker doesn't work on the trailer. There is a 7 pin round plug on the car, with a flat adapter to the flat pin on the trailer. I have had the same problem with at...

Hello Carol, The 7 way is for use with a brake controller and/or a trailer that has electric brakes. The 4 way flat is a basic trailer plug connector.
Connect as follows:
Green wire- Connects to the vehicles right turn wire harness & provides brake light and right turn signal on trailer.

Yellow wire- Connects to vehicles left turn wire & powers brake light & Left turn signal on trailer

White wire- Ground

Brown Wire- Tail/ marker/ license plate lights

The Blue, Red & Purple wires on the 7 way will not be used on the adapter, those are for brakes.

I hope this information is helpful.

Installed a wiring kit for a trailor but when i hit the brakes the lights go out on the trailor.any ideas?

You need to get a proper earth connection through the trailer. Ensure all your light is earthed to the trailer on the steel parts, then take a wire from the trailer plug to the frame.
Then on the car make sure you have the same pin as for the trailer earth going to the car earth pin, then find a good earth on the car and run a wire from the car plug to that earth.
This should stop your lights from flickering when the indicator is on also. So in short wire in a good earth for the trailer as well as a good earth for the car. Hope this helps, let me know how you get on.

No left turn or brake light on left for trailer truck works fine. No current in trailer plug wire

There are separate fuses for the trailer turn signals.Make sure they are good.They are in the under hood fuse block.If they are then check for corrosion in the trailer harness wiring.Hope this helps.Good luck.
