I'm going to hard wire my Whelen LED Blue Light. I'm trying to decide on how I will go about doing this.
The blue line is how I would prefer to have it run. The only problem is I don't know if it is possible to run a wire through defogger ducts and then to the switch panel where the fog light switch is etc.
The red line is a alternative. I would like to do this if I could find a grommet that would make it look clean.
I would need to know how thick the dashboard is, and the correct size grommet for SPT-1 wire.
Any input or advice for me? how would YOU do it?
