In the 2003 Marquis wiring diagrams Pages 50 & 52 (Ruby & Sapphire) show the TV & lift motor plugged into an AC dulpex outlet but with no ignition cutoff relay. Pages 55, 56, & 57 (Amethyst, Jasper, Emerald) show the ignition cutoff relay but no indication that the lift motor is plugged into the TV outlet. I think this may be a drawing error since the 2003 Marquis brochure shows all models have drop down TVs and, to the best of my knowledge, all models had ignition cutoff relays for the front TVs.
