Accessory Power

[TnTahoe]

For those with aftermarket hu and speakers that are not using any harnesses. I know the RAP powers things for like 10 mins but you lose that without the proper harnesses. So I was wondering how do you guys/gals play your a/v system with the key off since these trucks dont have an acc key position.

Not sure about your 2003, but for my 2001, the accessory position is just one click counterclockwise. Read your owners manual, the section "Ignition Positions" Hope this helps.
