I have a 05 tahoe. lowering my rear end and my rear housing is going to hit a black box with i believe 3 airlines/ or fuel lines attatched. what is this box? neccessary? cant figure out what it is.

with 3 air lines?.... there are no wiring clips. Seems like 3 air lines. lines look like they run over by gas tank. when I pulled lines off there was no gas. So I believe air lines but for what. I took the lines off and started the truck. Ran fine. Not related to the brakes because I pulled forward and back couple times. Dnt believe anything with trans but never left 1st or reverse. I would think a event recorder world need wiring to collect data. There are 2 large air lines and 1 small. Im thinking maybe some sort of gas take breather...... Just wild guesses. Im gonna have to trace lines to find out i guess

I believe it is an EDR, Event Data Recorder, similar to the black box in an airplane, records everything in a crash. Things like that.
