How might I go about doing this? I'm repainting the door to color match mine but once I do that I'd like to swap the old interior to it and install it on my car. Never touched interior stuff so this is very new territory to me, sorry if it's a noob question

 

You're swapping 99 EJ door electronics to a 99 EJ door? Are you trying to figure out how to take the switches off or are you swapping to a completely different door panel

 

interior as well as electronics, over to an entirely new panel. I'm just unsure where to begin regarding starting that swap and what it would entail.
