I've finally got around to reinstalling 4.9 with the caddy auto transmission.
The only snag is the metal vacuum line coming off the back of transmission.
Where does this connect to car?

I think you T that into your manifold vacuum.

Isn't it strange that after a bombing, everyone blames the bomber, his upbringing, his environment, his culture, his mental state but … after a shooting, the problem is the gun?

Does anybody have pictures of the engine bay on the drivers side that has a 4.9 & t460e transmission?

Plugs into base of throttle body with a short piece of vacuum tubing on the distributor side.

Cool beans!
Like aha it fits
Thanks dude

Sorry I missed your message earlier. I was downstairs working. Didn't have my phone with me.
It's the vacuum line from the transmission modulator valve. It's connected to manifold vacuum (or the throttle body, below the throttle plate..)

I believe that its the far left hose nipple on the throttle body rear.
