express windows /modules

[Ehodg66]

Adding relays to speed up the windows and then going one step further to add express up/down is a great mod, to me.
I know there are multiple threads on this subject and Gmachinz seemed to have the goods with his harnesses and modules. I know a few members had issues with him and he has since been banned from the forum.
My question is, has anyone attempted to do the express up/down setup on their own?
Did anyone purchase his harness w/ express up/down? Lastly, has anyone identified the express modules he used? (pic attached) He called them "solid state modules" but I cannot seem to find this item on line.

I'm aware of the autoloc setup but I've heard/read mixed reviews.

thanks in advance
