well i went to take out my TCU to ship out to Eurocharged and im like ok what happened to it. I guess this was strapped to it, not sure how it works or what it exactly is. Im sure its not a big deal but just in case is it ok to be strapped to the tcu?

TCU is shipped, just not sure when i get the TCU back should i strap this back to the TCU again and be done with it.
