I'm sorry I don't have the exact details...but when my 95 TC was converted to springs, an instruction sheet came with the spring kit that addressed the issue. There was a small circuit board located behind the glove box in the dashboard, and one cut one of the wires from it.
Darn shame I don't remember which wire, but maybe this hint will help you research further.

There are actually four types of springs used in the suspension system. They are coil springs, leaf springs, torsion bars, and air springs.
