Sometimes cars have vent intakes just below the windshield, and you could sneak the wires through the vents inside. Not sure if your Buick has that, but that is one route.
Oh wow thanks!You're doing spectacular work. This is the best project I've ever seen. Keep rockin' it!
Here are some old computer cables that I've altered to be the "mole richardson" plug that goes into the flux boxes. I pulled out the pins and bracket with some pliers. I glued some plastic into the end to give something to attach to the plates I previously made. This pic was right before I painted them.
