Vacuum line connection to what?
I have gone over my vacuum line routings in my poster size image and in the Mazda dealer service manual and cannot find where this nipple connection on the LIM goes. Nipple is in center of picture.



Any help appreciated.

Thanks,
Chuck

I thought that the EGR was the connection but wasnt sure. I took the EGR out.

Problem solved!

Thank you.

EGR has a vacuum line and, in '93 cali and '94s, also has the blue 2-wire connection. That's the EGR switch that just verifies that the vacuum signal to the EGR made the EGR move like it's supposed to.
