Selling products with no instructions

[modelsjeep2009]

I bought two products for my vehicle. These items need to be installed and hooked up to the vehicles wire system. Both items did not have the instructions and one of the sellers told me to look at You Tube to see ho0w to install it. Why does eBay allow these types of sellers to conduct business.

Ebay has nothing to do with what a seller sells except for items that are banned. Items sold are NOT required to give you instructions. If the item typically comes with instructions and your item did not you can either return it or do as the seller suggests.

Are these replacement parts or aftermarket add-on items? 

Most every item for a vehicle does NOT come with any instructions (alternator, battery, starter, carburetor etc.

Only usually does a Radio or Alarm come with some type of wiring diagram. But, with the advent of youtube, it should not be hard to find a video on most items.

Because everything today is digital?

Mechanics normally don't  need instructions on how to wire a product.  They can tell which wire is ground and which is power.

I can't remember the last time I purchased a product that came with printed instructions. At most you get URL to instructions online. And since most of the parts today are made in China those instructions are usually so poorly translated they're incomprehensible. So YouTube is usually a preferable resource.

I wire $600,000 CMC machines that don't come with instructions. Any info that is needed can be had by contacting the MFR for specs.

@modelsjeep2009,

Many items do not come with instructions these days, you have to go to a Mfr.'s site to get them and/or a video link.  When you buy cheap unbranded or unrecognizable brand named products from China, if you get instructions they will be hard to follow and their videos aren't that good either.  Even if you follow them carefully they may not work and some can cause problems with electrical systems or the ECU.

I agree with everyone else. Printed instructions are a rarity these days.
