So i installed my interceptor the other day by just plugging it into the obd2 port. Now when i turn my car on it says on the screen annunciators not loaded or something along those lines then turns on for 3 seconds and shuts off. what do i have to do to make it stay on. When it turns on it will go to the normal screen but read nothing for those 3 seconds

This is for a friend not me his car is a lsj

 

He called me yesterday and I told him what to do. Hook up the red wire from the plug that comes from the back. The one he didnt realize was in the box lol
