Removed Instrument Panel - Now won't start

[bwhite757]

Ok, so all of my gauges have not worked for some time. I decided to remove the instrument panel and make my own with aftermarket gauges. Problem is, now that I've removed the factory instrument panel, the truck won't start. Doesn't turn over, acts like the battery isn't even hooked up!

So what wires do I need to jump to get my truck to start again!?
