OK folks, here's the final results of the fog light install on my wifes' 2015 Nissan Versa Plus model.
All told, it was about a 4 hour project, as I was taking the time to carefully remove everything without breaking anything.
I have the benefit of having a 6,000 pound vehicle lift in my shop to help make things a bit easier also.
Before raising it on the lift, I opened the hood, found the fusebox compartment ( all the way towards the driver side firewall, found the ignition wire, a small red wire ) using a test light to make sure it only energized with car running, tied into that wire using a "clamp style" electrical piggybank, ran 3' of loose wire from that point, to tie into the modified harness and a 20A fuse before the actual kit harness.
Raised the car up, took the wheels off to gain less restricted movement to remove a bunch of push-clips and #20 torx screws about 3/4 of the way from the front of the car towards the rear, pulled the fenderwell guard back out of the way, installed the brackets that house the lights, installed the lights connected the kit harness, zip-tied the enclosed wiring tight to the car and out of the way of anything that moves, buttoned her back up, lowered he car and completed the tie-in from the loose wire I had left running to the ignition, covered the new wiring with the same corrugated plastic wire cover all manufacturers use (bought a roll at auto parts store), cranked her up and verified new fog lights, and all existing lighting worked properly, and called it a day.
I'll install the new stalk with the intermittent wiper feature later today and test it to be sure the computer picked up the signal.
I'll keep you all posted if the new "stalk" works as it should on this particular "Plus model".
Meanwhile, here's a pic of the end result. Enjoy!
P.S. Thanks go out to jas32 for suggesting using the ignition tie-in.
