I researched the installation of the Factory Fog Light Kit PN 999L1-4Z000 for a Versa Note and it appears to be fairly straight forward although I have one question.
Does the body computer need to be reprogrammed to allow the proper operation of the fog lamps once the installation is complete? The installation instructions PDF does not mention it but it shows a schematic that the wiring goes through the body computer module.
A while ago I installed a similar kit on my Jeep and that required a dealer reprogram to enable the fog lamps to function.
