So I went into a whole research mode a while back about this.
The first idea I thought of is have some motors and wire it to a switch or wireless switch in the cabin for fully open or fully closed, essentially not using the OEM actuators. This could still be an option but I stopped looking into it for other mods.
Second idea was the Mild2Wild controllers but that’s shot down as you have to already have NPP to use those. Then there’s the fuse pull but that’s the same where you already have to have the option to do it.
The biggest rabbit hole I found was from the
Corvette forums by a user named Theta. The corvette went from a vacuum NPP to the actuators before us and they still use the same actuators I believe. Literally the same actuator is used, Theta went into great detail on reverse engineering it and I believe all the information is there in the thread. A few members of the Corvette forum tested and used his system from what the posts say, little hiccups came about but not many actual systems were sold to the crowd. Sadly, Theta seems to have gone MIA years back and some assume the worst. It is sad but the idea and engineering behind it was amazing. I’m sure someone who can understand electrical engineering bits can probably do it and make sense but I can not. In my search, there’s
one post from someone who has a video that shows he got the actuator to work with his own setup but he never responded to calls to show how he did.
So yes it’s possible, imo if you don’t understand what Theta was doing then your best bet is the motors wired up in option 1.
