4wd after new carb and nutter

I am sure this has been answered many times. Searched and could not find anything right away. Installed a motorcraft carb. Where do i attach the red vacuum hose too? Mine goes into globe looking thing under battery tray

Hook the red line up to manifold vacuum...such as a tee coming off under the vac line to the brake booster from the manifold.

I did what dtn8tr suggests and got manifold vac off of the brake booster tee. I routed straight from the tee over to the red line--I had nothing going to the "globe" under the battery tray. I plugged all the lines coming out of the globe.

You won't be able to see the fork move. You can get all four tires off the ground and test 4X4, but the better way is to get in a parking lot and and turn a tight circle--once out of 4x4 and once in 4x4. You'll know quickly whether it is working or not.

Yeah...I just nuttered mine and installed a Weber recently and was cleaning up vac llines and inadvertently moved my line and didn't have 4wd. I put it up on stands to verify because I could feel the tc shift into 4wd. I traced back the line and found that I had put it on ported vac and it wasn't locking in...moved it and all was fine.
