Drilled the hole and got the grommet in and line run to actuator. Now to determine were the broken nipple goes to???? The pictures show the tee connector broken in the top left of photo. There is a hole in the top right of the firewall, noticeable in the photo. Could my broken mystery line go out that hose to a vacuum source? I would think it would be a A/C controlled source rather than constant engine vacuum. Hence the hole and the line going in that direction?????
