Re: 2003 silvarado need help
Your battery ran low and you jump started with a low battery, putting a lot of stress on your alternator. I would pull the battery and load test it after fully charging it and also have the alternator tested.

when hooking up trailers ,the problems are usually in the plug connections. It is very possible that there is a broken wire in a plug or the wiring in the car is different to the plug. If the lights of the vehicle all work then it is not a fuse but in the plugs or trailer.
the colour code for the wiring is on the trailor plug if its a 4 wire green is right signal, brown is taillights, yellow Is left signal, and white is ground. on the truck. check which wires on the truck are right, left, and taillight. the ground wire you can use any ground for the light system or hard wire the ground to the body of the truck.
You don't need a colour code as long as you have a test lamp or a voltmeter. Turn the side lights, indicators, stop lights, reverse lights, rear fog lights on individually and test for a positive wire each time. Label them with some paper tape and a pen if it makes it easier to keep tabs on them. All your lighting wiring is in the back of the car/truck/hatch, whatever. Your rear light clusters will lead you to all the wiring you need. If its any help, the rear light cluster bulb positions give away which wiring leads to which bulbs. You can see the colours of the wires right there.
Hi, 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.
You mean the truck parking lights dont work, or the trailer running lights dont work? Does the trailer just have tail lights or does it have front and rear side markers? I think you mean the trailer lights. Check for power at the plug,(Brown Wire) if there is power, then you could have wiring problems, but a better description of what works and what doesnt work needs defining.
according to wiring diagram no module . do you have pwr at trailor connector. should be green w/ white wire coming into trailor connector. ( I believe pin 7 on connector ground should be pin 5 and is white with black wire )
