I have looked through several threads and have not found exactly what I am looking for. I am installing strobe lights on my truck for times when I am on our construction sites. I have a 2018 2500HD Duramax and all of my available switches on the factory bank are being used by factory options. I have seen where some have used one of the cigarette lighter plugs or even hooked up to one of the homelink buttons to install an auxiliary switch but wanted to see if anyone has used other locations for mounting auxiliary switches. I do not want to use the homelink buttons nor do I want to use one of the cigarette lighter outlets...any thoughts, photos, threads I have missed, etc.
Thanks in advance!
