Well its not that easy, door modules have to be replaced, the door looms are wired different, so unless you're a wiring person forget it, you could if you have experience of wiring use the side indicator wiring to power the led's in the door mirrors but this also has some questions over bulb warnings as going from bulbs to led's, so maybe needs resistors aswell, but finding the folding mirrors alone is almost impossible as they dont come up on the bay often, I have the new covers but not got motors yet
I've stuck the new J door module on & being wiring guy it was fun for even me, not impossible but you really need some know how for this mod, most pins have to be moved locations & I got number of errors, so swapping modules soon to see if its module faulty or compatibility issue with car modules given newer version of door module & older onboard modules
I'd wait until I've checked this if I was you fella
