I am having some confusion on which is vacuum port 10 and which is vacumm port 11 on the Service manual diagram on the EF & EC7.
Anybody know which is which 100%.
The lines in question go to the E.G.R.control solinoid and connect to the underside of the vacuum multi line rail below port 7, 5, and 9.
This is on my 1989 240sx ka24e single cam motor
Thanks
