IMRC Troubleshooting - Code P1537

1998 F150 4.2 186K miles

Truck running great. Check engine just turned on gave P1537 code

I need to know where the vacuum lines are that go to the IMRC. Is this the large (about 3/8 inch ID) rubber 90 degree angle that comes off underneath the throttle body and heads towards rear of intake?

I would really like a full diagram of the vacuum lines especially the lines controlling IMRC. Trying to avoid removing the intake to find the problem.

Thanks for any help.

IMRC is electronic and vacuum. Each back has it's own...
