High Idle option

[chessy56]

Looking to buy a new D-max. Most of the ones I'm seeing on the lots have no high idle option (although I can factory order it). Can this option be added after the fact by the dealer or myself?

(Same for roof marker lamps- although this issue isn't specifically D-Max related....)

yeah it's $200 for the option that is pure software. I have it on both of mine. Not sure about adding as SEO accessory or if a guy could get it in through cloned programming somehow?
