I used the generator version for my frame-off 1950 which was completed in 2011, I have had zero problems with it. Fairly easy to install and comes with turn signal wiring. I heat shrinked all the connections, carefully ran and supported everything and it has been a good harness. I converted my truck to 12-volts with the installation of this harness.
