No ingition and no dash lights when attempting to start

Tweet

I have a 2000 dodge ram. It was involved in a front end collision. I replaced the hood, grill, fenders, radiators (trans, a/c condenser, and engine), and the radiator mount. I kept the old wiring harness. Upon completion, the truck started and ran. I drove it twice. During each trip, the engine died, but restarted fine. Upon completion of the last drive, the truck now shows no dash lights and a I get no turnover. Radio is dead. The blower motor worked for a while but no longer does. Headlights work, horn works. Originally I thought one of the grounds was bad. Rechecked the 4 that I could find. Reattatched each. Still nothing. I have pulled all fuses in the engine compartment fuse panel. All show 0 ohms. I am thinking it may be an attatchment for the ignition switch. I have check that to no avail. If I could get any suggestions, or steps needed to verify electrical paths I would greatly appreciate it.
