There are two yellow lines coming out of the firewall. one is bright
yellow and the other is a darker yellow. Are these for the door
locking system? If so where do they connect to the vacuum system?.
They'd tee into the big hose to the brake booster somewhere, through
check valves. The brig
Yes, I believe that the yellow lines are for the locking system. It
really doesn't matter where they go injust get them into the vac system!
How is your transmission shifting? Or your ACC system? Both of these are
also vacuum operated.

Vacuum Door locks - do not function.
I think the lines in the engine bay may have been disconnected by PO I am not
sure and I do not have any diagrams or pictures to look at. Is there a site
with good pictures, etc. or is there a good book I should be purchasing?
