What do you have to do to de-activate the air suspension light and system after converting the air suspension to coil springs?

There is an air suspension switch in the trunk on the passenger side. You can turn it of . there is also an air suspension fuse under the hood in the fuse box on the passenger fender well. you can remove that 30 amp fuse also.

in the fender well inside the trunk on the passenger side behind the suspension switch. remove the carpet off the side. there is a module with two conections, one grey and one black one. remove the black one. there is one green, with light green wire. cut that wire and reconnect the harness back on. the air suspension light on the dash will go out. this is for 1994 and before Lincoln town cars. on 1995, the module is behind the glove compartment. do the same like on 1994. cut the green wire and the air suspension light will go out. this is the best way to disable the whole system.
