Question on these switches. 1) are these switches carrying load, or are they a negative lead style switch. 2) are the toggles like the 2015/2019 year trucks? 3) if I wanted to use them for an earlier year vehicle, just short of custom installing it, can they be wired to an external relay if you just had the pigtail wires that connect to the back? Assuming adding power and ground for lighting for the buttons. Only reason I ask, is because I have a 2017 and I have a couple places I can mount this as I like the factory look. The upfitter for my vehicle doesn't work as the relay wiring isn't populated and it's a bigger headache getting it setup. Appreciate your feedback.
