    I purchased this universal wiring harness and overall i give it a 8/10 rating. I was unhappy when fully streched out the harness barely reached the back of my truck which is a regular cab short box Dodge. So i had to do a quite a bit of wire extending in order to wire in the brake and turn signals to the rear. The only other issue i found was the black they label the wires with were extremely hard to read, i wish they would have used white labeling on the dark wires and black on the brighter colored wires. Overall i am pleased with this product and the ease of installation. I most certainly would purchase this product again and will do so in the future on my next project.

    For the price I cannot complain about the harness. There were a few wires that did not reach the tail lights and dash switches so I had to splice additional wire in. I do wish it came with new connectors because my headlight switch plug came apart in my had when I pulled it from the switch. The document included consists of a black and white extremely basic representation of some, not all of the primary connections however, What I could not discern from the rudimentary instructions I was able to cross reference from the painless wiring harness site to ensure my connections were proper. Overall, if you have wiring experience and can solder your own terminal ends this is a good harness fir the price.
