You can use your VOM to bench test the new switch and figure out the connections before installing it. Check the resistance between the terminals to determine which two are connected. Click the switch and check again. One terminal will be common (connects to another terminal) in both tests - that's the one that connects to the light switch. The other two terminals connect to the low & high beams - doesn't matter which one goes where.
