This is in the driver’s side engine compartment, near the firewall.

One connection goes to the bulkhead of the firewall and under the dash. The second one (I believe) goes over to another T connector by the left valve cover. But I can’t find where the third line belongs. 2001 Sonoma 4wd SLS. The red plug is what I put in to prevent a vacuum leak for now. Thanks!

I had this issue one year ago, and the forum expertise came to my rescue.....

Yep, right where you said it would be!

Much appreciated, manbearpig and Big Buford. I’d never have found it otherwise.
