New to the forum and I am hoping you guys can help! I have a 2005 Silverado 1500 LT that needs replacement shocks. Looking at the fronts and rear, there is a wire harness attached to both, however, I'm having a hard time finding replacement shocks with the same configuration.

The existing shocks are a Delphi brand that I can't seem to find anywhere. Are there non-factory parts available? I'd like to keep the electronic suspension setup if possible. I've attached some pics of what's on there now.
