2009 chevy expres trailer wiring harness

some van don t have a ground wire. hook up to trailer put jumper cables to frame of trailer and van if works install a ground wire plug

Try a couple of new bulbs and hope it hasnt burnt a wire in the wire harness.

The fast flash is often an indication or a bulb out, but a burnt wire will cause the same

simple way is to by a trailer harness

this will allow you to disconnect your brake light harness and adapt the trailer harness w/o cutting any wires

first never plug back in to that trailer, it may have bad wiring, the next thing to do is to check the front and rear bulbs, they may have blown,if it was a fuse the signal inside would not blink,so this tells me you may have blown the bulbs,and also this trailer is unhooked from the van and lights still dont work?. good luck.

Also try http://www.etrailer.com/faq-wiring.aspx. They have a great website with lots of info. With the tow package, there should be a plug under the dash... far left above the emerg. brake petal. The harness that plugs into it should have came with the truck, or you can order one to fit it. Did thew truck come with a 7 pin plug on the back? If not you can order one from the above mentioned site. They also have the wiring colors.

what are you asking? how do you get the lights to hook up to the back of your truck? you may need a pigtail connector to hook the trailer up and have it work properly.

there are kits available at auto parts stores that plug into existing brake lights. Some kits have modules that are necessary for proper signal to trailer lights.

vehichle is equiped with plug mounted under rear,you need to go to dealer or parts place and ask for adaptor and they can help.

Go to an auto parts store and see if you can have a look at some electric brake modulators and trailer connectors they almost always have instructions in them that detail standard colors for any install. The standard diagram is often right on the back of the connector package.

Yes you will have to hook up a adapter. The only reason that you would not have to do this is if your vehicle came with the complete tow package, meaning shocks and tighter springs and everything else. But most of these models require a adapter to run electric brakes
