So, the night I completed my install, I didn't put things back in order until the next morning. The next morning I opened the trunk and I noticed the JMS had a green LED glowing. I emailed Ted Jannetty and asked if I might have not installed it incorrectly. He replied back" Fuel pump driver module is always on, green LED always on, you installed correctly" Mine never shuts off, I bought mine in late spring of 2023.
