Your question is not clear, 2002 trailblazer has a towing harness, in order to find each wire, use a ohmmeter and try out each application.

In case of male harness of a camper you can test it with 12 volts in each wire looking which light is on and if it is different position cut wires and make similar wiring

What is the function of the 8 wires for the factory rv plug?

The 8 wire plug on newer models is for trailer hauling. The wires give power to the following; break lights, marker lights, backup lights (as equipped) parking lights, electric breaks (larger trailers will have these) one wire is a ground, and, through a positive wire, will trickle charge your trailers house batteries also. There is an industry standard to wiring one of these plugs, so you should be able to purchase any "newer" style trailer (tent, tow behind or 5th wheel, or camper) and the wiring harness will be wired accordingly. Any RV shop or auto shop should be able to provide a schematic for the wiring if you require one.

I need to install a trailering plug for a camper that I tow. I'm trying to figure out if I can wire it myself? I drive a 2006 f150 pick up.

Go to the auto parts store ... they have or can order for you, a special plug that you insert into your existing wiring harness that will probably include the standard trailer plug. There is an outlet at the back of your truck for this add on.

Thanks for your interest in ... please remember to evaluate my response. Thanks

I have a 06 town & country with a four pin wiring harness. Our pop-up camper has a 7 pin round plug. I used an adapter to connect them but it caused a blown fuse; was told by shop that would have...

I'm assuming your pop up is big enough to have electric brakes, thus the 7 pin connector. If it doesn't, you can use an adapter (probably like you have) provided the 4 pin was wired correct in first place, but if not, figuring out what's what, shouldn't be difficult. If you do have brakes on the trailer, then the law requires it to be wired such that the brakes are operational. If your thinking of tackling this yourself, and are reasonably familiar with 12 volt wiring, we may be able to help, if not, any hitch installation place, or RV center should be able to give you a reasonable price to wire it properly for you.They usually know what wires to splice into without replacing any harness, as well as have knowledge of proper installation for electric brakes as well. Usually ends up being a choice of a higher labor price, but less time for those experienced in doing that, or paying an inexperienced guy a lower labor rate, but takes him twice as long. personally I'd go with those who do it all the time.

With 4 prong and 3 extra, that will give you what you need for 7 prong for towing RV. If your not too experienced in that area, a mechanic at any trailer place, or hitch installation place or who knows RV wiring, should be able to do it for you in about 1/2 hr. or less. Testing the wires from your truck for what they do as in right , left, stop, running/taillights, etc is about the hardest part, and the 7 prong usually comes with what terminal does what.48e2ffb.jpg

Tow bar trailer socket wiring connection point to car wiring?

The connectors for towing wire harnesses on foresters are generally on the passenger side, below the rear taillight inside the cargo space. some require pulling up the foam block that is between the spare tire compartment and the taillight. Check where you replace the tailights from inside the car, if there isn't a matching connector hanging out there, check around the spare tire compartment, see if you can remove the carpeted foam block next to the compartment and find the plug under there.

2009 chevy expres trailer wiring harness

Ask dealer if it has a towing package on it. If it does, you usually just pop fuse in under hood for electric brakes, and harness to adapt into is usually near or at rear bumper. Even if it doesn't have brake wire, you should still be able to install adapter at rear,for lights etc. which is available from dealer or auto supply places, then you may have to run electric brakes separate.
