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
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?
