Hello,
Webserve explained well, however there is a few other bits to be added...
In tyhe trunk compartment remove the trim panel (Behind spare)and find the rear axle electrical connector. ( '92 black 8 wire, '93 white 8 wire connector)
Remove the following wires:
YEAR 92- Pin 1 (Brown/ Blue) Pin 2 (white /gray) Pin 5 (yellow/brown) Pin 6 (yellow /blue)
YEAR 93 PIN 1 (Brown /Orange) PIN 2 (White/Gray) PIN 5 (Yellow/Orange) PIN 6 (Yellow/Blue)
Tape up the wires. Becare ful that you dont remove the brake pad sensor wires.
Done; replace trunk panel.
After you have removed the slef leveling assemblies (Shocks) you should remove the crossover pipe from above rear subframe.
Find valve block, and disconnect rear suspension pipe from valve. Cap valve with bleed screw (part no. CAC 8293) . After capping the valve you should remove the pipe that leads back to the SLS.
Start car and look for any leaks.
