Question: LS3 Plug n' Play Harness Relay/Fuse Box Dear Sir,
I am installing a LS3 crate engine with the GM Plug n' Play wire harness. I have a question about the fuse/relay box in the kit. The fuse/relay box has two vertical posts on the right side in the photo. They are for connecting various components the installer desires.
The question is: Are these two terminals always "HOT" or are they energized when the ignition is "ON"?
Thanks for any insight to this question.

Also, Gandrud sent a PDF of the wire harness diagram and entire LS3 system diagram. They need to be loaded to a thumb drive and taken to a print shop for printing. Way to much info to print on a 8"X11" piece of paper.

Hello there Sir! Sorry to revive an old thread. I've had the swap as well but I wanted to add an accessory directly to the fuse block vs an add a tap on the slot. It would be a great help if you can send me that PDF file of the wire harness diagram.
