Yeah looked into that too, mine has not got that. :(
I'm considering running new wires and adding a switch to the dash so I can have something for light, and maybe just running new power to my mirror control. Not the preferred method, but I've been 2 years patient with this.
Somewhere there's a DC10 struggling to get off the ground. I'm not a fan of wings on street cars, I like low key spoilers, but not something that you have to custom order from Boeing.
