Installed my Kahtec module last week. Took less that an hour. Wired to my 3rd brake lite in the wing. Simple install...just be careful removing the interior panel on the hatch, the plastic things aren't fragile but will break . I did not use the included blue connectors...I used in-line splices to take up less room in the wire bundle. I bought the flash then steady module. It flashes about six times then goes steady. You have to take your foot off the brake for 8 seconds for the flashing to reset. Works great.
