LS wiring to truck?

So im almost done with the LS wiring...Where do i go from here? Obviously, it needs to be tied into the truck itself now. Im assuming its from the block where the wires come thru on the driver side. Is there a pinout somewhere for that? What connects from the ls harness, to the truck harness for KOn,Koff etc? Im sure im just overthinking it and looking right over something obvious, but someone point me in the right direction please.

Keith

Hey Mongo,
Can you elaborate on how you got constant power at the junction block? Not sure what you mean by that.

Thanks!

Hmm... you threw me off, my junction block is on the passenger side fender. When you said firewall, I thought you meant the fuse block.
