You didn't mention which engine, but I'll assume DE. The 'U' shape goes from the throttle body to a hardline attached to the intake plenum. The 'S' shape goes from where the large water intake line attaches(on intake) to somewhere under the intake. It shouldn't be hard to tell once you have all the others hooked back up. Sorry i can't be more verbose, this is from memory.
