I'm putting the carbs back on my 07 and on the lines that go to the top white vacuum ports have an extra 3 way connector so there's 3 ends. I can't find anywhere the third hose goes to. Anyone know where it could go?

Have you been using the routing diagrams in the wiki? If not, they are here... maybe they will help:

Hopefully these photos of the carb plumbing on my 2004 model will help.

I've looked at many routing diagrams but I can't seem to find one where it has 3 end on the lines that go to the ports. The only thing left that I could possibly put a line on is switch the lower line (supposed to be next to the solenoid) over to the left so the ports going to the top can reach the lower right port (next to the solenoid)

That picture doesn't look great but if you open the full picture it's of my top lines
