New bags now won't start? WTF?

[ironadict]

Ok so I just got done paying my air ride some much needed attention. New ss-7s up front. 2 new smc valves and gauges for all 4 corners and tanks (no power ran to them yet)

Finally get it all buttoned up and go to start it and NOTHING. turn the key and literally no noise. the radio turns on when in on position but that's it.

My first thought was ignition switch. So i pulled it down to just the wiring harness that plugs into the back and essentially hot wired it by jumping the bat,ign, and sol wires and nothing still so it must not be ign switch right?

All my fuses look good and battery is solid so what next? Starter solenoid? Where is it located on the 71 c10? I remember My 63 Lincoln had it on the side of the engine bay and I'd just jump it and it would start right up. Same thing to test it on this? It would be great if someone can help me out here cause as you can imagine, I'm dieing to get out and try out these new bags and gauges.
