If I'm not mistaken, (and I often am) the harness runs under the transfer case along the backside of the crossmember and there is a bracket that bolts to the topside of the crossmember close to the frame rail to hold the harness in place. The connectors tuck up insde the right frame rail. Did you reroute the harness over the transfer case? Regardless of the harness routing, you are missing that small bracket that secures it to the top of the crossmember. If it wasn't raining profusely at the moment, I would go out and crawl under mine to scope it out for you!
