vacuum source needed
I'm installing an aftermarket cruise control in my '99 e150 with 4.2 v6, and need a vacuum source. Other than the obvious brake booster line (which is not a recommended source), where is an accesible vacuum line on this engine? One line I pulled off to check turned out to be a cooling line, and others appear to be fuel lines, and I can't see anything obvious.
