Window indexing retrofit/aftermarket kit

[RoadsignDS9]

Not sure if this should go here or the interior section.
Looking for either information on retrofitting window indexing or any aftermarket kits.
I searched here and found information on 1-touch up/down but not the indexing function. No luck on google either. If it matters, it is for a 2nd gen f-body.

Coach controls has it built into their universal wire harness. It uses the door jamb switch though and in my mind that is too late for opening. In a perfect world, you would do this with late model electric latches and door buttons.

I have no experience with making this work.

Great, thanks! That's more information than I found. Since pretty much everything we do in this hobby is modifying, maybe the setup you mentioned can be modded for a different opening activation.
