2002 z28 camero LS1 6 speed manual 35th year edition

Trace the lines out to see what they are but this does not look factory.

Any one have a clue

It is a air compressor for air shock,s

So is it a stalk part or is it for aftermarket suspension becouse it runs up twards the front in the side of the car behind the passenger door that's where I lost track of the 4 lines

After market part,

Figured it out its for my convertible top it's a valve to release it if it gets stuck
