I'm saying this from experience when i was removing the JB3 and spent an hour trying to figure out why my car wasn't starting :P
I came to the same conclusion after removing all 4 sub connectors. I got nervous for a few seconds when I realized what I had done. Referred to the manual to connect correctly. I'll do 1 sub connector at a time all future work.
