first off ive been a long time member at the diesel place. nobody really answered me there so i was like ok f that place. i am trying to gather up info and parts to build a cc k30 4x4 with a duramax. engine seems easy enough just basic wiring and the ecm reprogrammed to turn certain things off fuel system and the pedal swap. im having problems figureing out how to keep certain things and what i need to keep them. first the the 6 speed i really need to keep the tapshift and the tow haul. next i would like to use a push button transfercase out of of the same parts truck. i know there left side drop. got that figured out plan to use a newer dodge front axle. truck is going to be daily driver so i dont have to have the strongest front axle just one that works. i also plan to swap in the aam rear. so my question there is what do i need to wire up to control the transfercase. gauges im gonna use all aftermarket. for a gauge for the tapshift i plan to use the quadzilla monitoring screen thats similar to edges and banks (just the monitor of course). lastly cruise control how do i keep that. everything else should be native to the truck and not need anything from the parts truck. sorry for the long post and thanks.
