But, the compressor switch is to be turned on, correct? To complete the circuit. Right?
No I don’t think so. There is no switch so the connection can be removed and insulated against a short to ground. When you order the conversion kit there will be instructions. Earlier models will allow a wire to be cut to prevent the instrument cluster showing the air suspension light and the message. Later models will not allow that and keep the light on. Black insulation tape circle over light makes it less anoying. The instructions with the kit explain what you have to do.But, the compressor switch is to be turned on, correct?

As Town mentioned, you don't, at least not on the latest generation of TCs. That's why he mentioned the black tape over the error message (I just ignore it on mine). Now, there are some folks who have done some workarounds if you are good with searches. One involves leaving the solenoids in the car (wrap them in plastic bag, zip tie out of the way) with wiring plugged into them, and then taking apart the height sensor components and manually adjust to the proper voltage reading for the correct height (2.8V maybe?) and secure the parts in that position with duct tape or whatever. Then turn on the switch in the trunk and the car thinks there are air springs at the correct height. Someone else was trying to find out what the resistance would be of the height sensor when set for the right height and replace it with a resistor. Another guy somewhere mentioned (I think this may have been a Grand Marquis) he left his height sensor in place and since the car on coils was the correct height, it worked out the same way. And yet another guy I seem to recall mentioned being able to disable the message with Forscan.Another stupid question. After converting to coil springs how do you keep the dashboard warning light off?
Babyburr, since your car is new to you, just turn off the switch in the trunk and drive it for a week. If the rear starts dropping then there is a leak and you are on borrowed time. If the rear stays up, then turn the switch back on and have confidence that you won't need to do anything to your air ride for some time.
