I looked at some other pictures I took yesterday and the line comes off the back of the intake manifold and through what looks like a simple splitter, but could be a check valve. I'll get a closer picture and post it tonight. The other line runs through the firewall. I haven't chased that line to see where it goes yet.
No windshield, windshield wipers or engine power to verify if this actually works. ;-) Maybe I can report back in a few months.
