Idle drop

[pursuitoftime]

All I need is to know where the IAC is on my 2015 DF175. When I start, it idles up fine then drops down to a no idle. No good when you want to get away from something like a bridge piling on a quick start. I have to disengage the shift to bump it up. I thought I'd clean it before determining if I need a new one.
Also, where do I pick up a feed to adjust the duty cycle?
