Very pleased with ETrailer service and follow-up. They packaged and shipped the trailer wiring harness I ordered pronto, and sent it off via UPS Mail. I should mention, however, that the postal service side of the delivery was not good: Most of the time the post office is OK, but this time they "round-robined" the package to several post office locations -- and then it was delayed for 5 days at the last post office location: 1. I finally had to call ETrailer regarding the interminable delay; and their customer support did look into it, and the parcel finally arrived soon after. In all, I'll be very happy to order from ETrailer again. I think they're a solid, reputable outfit. With the next order I'll probably pay extra to have the item shipped thru an expedited UPS delivery (rather than rely on the post office). 854069

Everything you need to add a standard 4 wire trailer connector to most any vehicle. Inline tap connectors are provided if you already have a factory bumper mounted connector, or simply splice it to the end of the taped off harness. The included dust cover and plastic sheath is a must for any trailer connector as dirt and corrosion is the number one cause of faulty trailer lights. The price may seem a little high, but you will spend alot more acquiring the supplied parts in the kit. 847511

I give three stars because the wire length is too short for use on the Astro van. You’ll need to extend the length by an irritating foot. You’ll also need to extend the right side blinker wire by 4 feet to reach the harness near the ceiling which contains the right side blinker wire. The quality is good, but I would have paid more for longer leads. I would make all the conductors 4 feet longer and up the price. 652479

The harness comes with a adequate length for making connections. The connections could be of the compression type, rather than the type used. This would make the splice area smaller, and easier to cover over. 457196

  • Looking for Trailer Hitch for 1999 Chevy Astro That Doesn't Extend Past Bumper
    I'd recommend going with a Class III hitch like the Curt # C13035. A Class III hitch with a 2 inch receiver will allow both a higher capacity than a Class II like the # 90231, but will also have a much better selection of hitch mounted accessories available, such a cargo carrying trays or bike racks. A Class III is usually not any more expensive than a Class II, so there's really no reason not to go with the alternative that would allow you more options and flexibility. As you can see...

If you need wiring, I recommend Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C55411 that splices into the vehicle's wiring behind the Blazer's tail lights.

  • Installing Trailer Brake Controller for 2005 Chevrolet Astro Van
    Since your 2005 Chevrolet Astro van did not come with a factory 7-Way trailer connector, it is likely that the bundle of wires you found at the rear of the van are not fully connected. Sometimes wires will be ran in case a vehicle is equipped with the tow package, but if it does not end up equipped with the tow package, the wires may never be connected. The best solution I can provide that I know will work for you to install a trailer brake controller and 7-Way trailer connector is...

  • Recommended Trailer Hitch Receiver for a 2004 Chevy Astro Cargo Van
    I did some research on 37042 that you referenced and its a Reese trailer hitch that worked with the Chevy Astro Extended Body 1990-2005. It's currently obsolete now. The Draw-Tite # 24773 you also have referenced will only fit 2006-2010 Mazda 5's so I wouldn't recommend this for your 2004 Chevy Astro Van. The most popular hitch we currently offer for your 2004 Astro Cargo Van is the Draw-Tite # 75122. It's a Class-III hitch and has a towing capacity of 5,000 pounds and tongue weight...

Consult your vehicle owners manual to determine the official capacity of your specific model.
