This is a challenging do-it-yourself install if you haven't worked on car wiring (which I haven't). I'm a very capable do-it-yourselfer around the house. The instructions were really pretty good, but a few things were unclear. The wiring T-harnesses made most of the connections straight-forward. The most challenging part was tying into the single parking-light wire. If you have expertise with depinning a connector so you can splice into a wire it is probably easy. This was new to me so it was a bit of a struggle. In the end, it was a successful install. The starter has good range and works great! This would be a 5-start review expect that there was a defective valet switch in the kit. I asked the seller to send me a replacement. They sent an entirely different switch. In the meantime I had found one on Amazon and ordered it so I could complete the install.
