Supposing you want to use Oraclize with a consortium Ethereum blockchain network, like in the simplest case with your Truffle development environment , you have to do the following steps:
git clone https://github.com/oraclize/ethereum-bridge.git
2. Start your Ethereum Bridge, with the network url and an account, like for Truffle:
./ethereum-bridge -H localhost:9545 -a 0 --dev
3. At deploying with truffle, copy the OraclizeAPI_05.sol locally.
4. You can practically use the same code as on a live network, in the Ethereum Bridge window, you can check the sent and received transactions as well.
A very simple implementation can be found under EthereumBridge in the following github repo.
