What is this part and what is it supposed to do?

What is your question?

SN:fq004bacfa5a meid:a100004bacfa5a P/n: s3000-s p1639 Fcc id:2aaq6tc05 I recently bought this truck the part has a constantly on green and red light even an hour after you're turned off the ignition and no keys are on. On a recent long trip up I noticed at 55 60 65 70 75 and 80 one of the lights would start flashing. I took a back to where I purchased it from as they said they would give me a new battery when I purchased the truck and I told them these lights were why a new battery was needed. Well they said they fixed it and there fix was putting a black piece of electrical tape over the lights and shoving it back under the dash. I found this when I took the fuse box cover off and there is a cluster of messy wires underneath. I found the wires connected to the I took the fuse out(red)that's related to this part and the lights are now off. There is a loosely attached ground (black)wire and a plug of which is not connected. The part/plug has 7 wires: green, yellow, white, orange, gray, red and black. The red wire is somehow connected to the plugin that is used for the scan tools. My cruise control does not work. No lights come on when I press the on button. I'm thinking these two might be related. I'm not a technician just a lady that as a little girl loved to help Daddy work on the cars. So I know a little, just enough to know when I need to stop and let the repair man take over. If on the right track can you advise where this part should be plugged into. Thanks, Pamela
