My truck didn't come with a suspension dump switch in the cab, and with the amount of drop/hooks I'll be doing, I'm gonna need one. I had my local Freightliner dealer pull up the dash switch needed off of my VIN, and this is what I got from them. An electric switch, which they said I'd have to wire up myself. So I'm to assume then that my truck already has the necessary components & plumbing for dumping all four rear bags.
As technically inclined as I am, my only issue is that I'm not sure where I should begin wiring this up to, since I don't have any schematic or anything. My only assumptions would be to either wire to the breaker box some how, to the ABS, or to the leveling valve. Pictures are below of the switch. I'd really appreciate some guidance. Let me know if you need more info. Thanks!
