Trying to do this on my 2014. I know about the Fog relay terminal having to be bent out and up to connect on side of the wiring to. Problem I'm having is finding the "best" switch-on HOT power source to connect the other side to. No heated seats in my TRD so it looks like I may not be able to contain the jumper within the small relay/inverter box. Is it ok to connect it to the inverter(square box) location in the same small plastic box?
The other spot that I'd think would be the parking lamp fuse....but it located inside the truck under the steering column. Really don't want to cobble up the wiring on this new truck.
