HELP WITH HEATER LINES

I have a 1996 f150 with a 302 engine. I have 2 lines from the heater coil hoses that have been capped off. I am wondering where I can find a diagram to show me where they go. Also I have two capped ends coming off the throttle body on passenger side that are capped also. Please help me to find where these lines goes.

It would be the heated plenum your truck needs to run well in cold weather.
Consider hooking it all back up.
The computer will be happier.

These are the hoses that were cut and capped. Also look closely and there are two nipples coming from the throttle body. Where do they go.

To the heater hoses that are plugged???

The PO even left the spring clamps there for you to hook it back up.

For the benefit of those who will find this thread in the future, The upper curved hose from the tube that is attached to the alternator goes to a throttle body nipple just underneath the cover on the throttle linkage, on top. The lower molded hose that is cut in half and plugged in the picture goes between the bottom throttle body nipple and the outlet on top of the temp sensor. The nipple between the two TB intakes is a vacuum line nipple.
