Ecs light on after lowering spring install

[2manytickets]

I just installed lowering springs, and now I have an Ecs light in. I double checked and all of the connectors are in and tight. Any suggestions?

Any help is appreciated.

follow the wires. either upstream connector is loose, or one of them got sliced during the install. most likely the fronts, shock removal not necessary for the rears.
