There were some anomalies when reading voltage through the fuseboard where the starter relay was. The 09' manual showed it opposite of where battery hot was and I reversed the relay to align with the manual orientation. I don't have it all in front of me to reference. Essentially battery hot was supplied in the opposite corner.

In terms of fuses and relays, the unneeded ones were not put into place. ABS, AC, etc. Don't think that the fuses would need to be there but maybe?

Curious and will try the X1-52 wire and X1-1 through the NSS.

So if I attempt to bypass the ECM and relays, how do I get this thing to run?

I'm a couple hours away from the truck, so won't be able to try things immediately.
