Installation of an auto all windows up Module

[gammafrench]

Hello all,

 

I have a window closer module and want to install it in my 2017 Silverado so I can close all the windows from my remote. I can already open all of them with an extended press of the remote's unlock button, but want to do the same in reverse with the lock button. I was thinking it could be wired into the driver's door, connected to the window switches, but learned (or may have re-learned after I forgot) that pretty much everything is controlled by the BCM.

 

Has anyone installed one of these before? I understand it can be an option with alarm systems. Any help would be appreciated, schematics, etc. I already have the "Body builders service manual", but it doesn't seem like enough information. there should be schematics somewhere with pin-outs of the sockets on the firewall under the dash.

 

Thanks!
