Nick, Unfortunately the directions you receive with the window motors is vague with no diagrams. To make matters worse the new units have a different mounting arrangement than the originals. I would not recommend that this procedure be attempted by anyone who has not successfully completed the installation previously. Any regulators purchased from us include live tech support, never the less, I still recommend installation only to qualified individuals. PS: the window regulator installation procedure is among the titles of our upcoming DSV Video Repair series scheduled to be released early next year.
