Hello All

Hoping someone can help me with this. I'm looking for a picture of a LS3 ECU fuse box with the lid off so I can see where the ground wires are getting routed to. Hoping someone has easy access to it and could send me a couple pictures ?

I'm having a hard time getting my blueprint LS 427 to come to life. ECU seems fine, no codes but no spark either. Checked out a lot of the wiring and I modified my fusebox but would like to remember how the original ground wires were terminated in the fuses.

Any help would be greatly appreciated!

thanks
