Well again if you can share a picture we can help...

But, in the meantime, there indeed are just two lines for the lock system. The solid yellow line goes in to the driver's door to the center connection on the master switch. The yellow with grey stripe goes to the vacuum reservoir. They should be attached to a yellow check valve with two connections on the firewall facing side, one connection on the engine facing side. Your climate control line is green with a yellow stripe I think it is. It often shares a 4-way connector with the locks.
