Starter Wiring Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 6.0 with a PSI harness and am having trouble wiring this up correctly.
I have the main hot from the battery on the main post, the 2 black wires on the same post (per PSI instructions) then I have the Red wire that comes from the drivers side fuse block - this is where I am having an issue. If I put the red wire to the main post it doesn't turn over, if I put it on the small post of the starter I get it to run the starter but even when the key is off.

My troubleshooting is either the wiring at the relays is wrong or I am missing something altogether at the starter. I should only have starter full circuit with the key in the on position....
Any help is appreciated.
