I do like an online thesaurus, lol, but what one persons idea of a hard job to do isnt neccessarily anothers fella, but if you're fairly technically minded then yeah its easy just time consuming, but if you've not got the latest door modules then you need schematics aswell for newer version as they dont match pin for pin unfortunately, I've tried swapping & didnt match up the modules capabilities with features on the door, so got some pages printed by local stealers for later modules to inspect, once I know then AS will know, if anyone can do before me then please post
