Re: PTooTi's 1996 Ford 7.3L gas E350 Eldorado - Aerotech
In my aerotech there were no wires under the fiberglass trim that was held to the wall by the window frames. You can see the white panels in the pic I posted. That trim was fairly thin and would show any wires underneath.
The only wiring at the floor level was two wires running from the back going to the side marker lights.
