We have sold over thousands of harnesses. If you look at sold after clicking on all our different harness auctions and add them up you can see for yourself. When you buy from California, click the members name and you will see he is really based out of china as a member. Then click their feedback and click the negatives and read for yourself. China sets up in California because they know you wont buy from them if you see they are from China. We have lots of complaints from customers saying they returned their harness to them because they offer no tech support and know nothing about these harnesses. You can message them and see for your self. We also sell thousands of fuel injectors every year too.
