Wiring help

[Stephen717]

So I got my engine bay wired and as far as I know everything is hooked up right. The only thing I noticed was that during the wiring process I didn't hook up the junction block or fusible link. I figured since the truck was running fine without it when I rewired it it wouldn't need it. but now when I turn the key I don't here any indication of the truck even remotely trying to start. can anyone tell me where I went wrong.

thanks,
Stephen
