82 with a 351 w and I would like to replace all of the vaccum lines under the dash while I have it removed. Previous owner cut some of the lines and I'm not sure how to reconnect.

Yo Jolene82,
I haven't had an opportunity to WELCOME you to FSB!
As packagerjr advised to help you troubleshoot your 82, here's;
EEC 3 aka EECIII Testing, vacuum & wiring diagrams, locations, etc in an 82 by Tommy @ Wayback Machine
"Woe was me, when I found out my 82 Ford Bronco was an EEC 3!
I had searched all over the engine compartment for the infamous "self test connector", only to find NONE.
Finally figuring it probably was a pre EEC 4 system, my disappointment turned to reality, when I discovered the printed EEC III label on the ECU."

Is that for the the HVAC Control Panel?
For a YARD SEARCH on-line, I use;
Quality Replacement Parts | Find Used Auto Parts | Online Locator
A yard that uses Hollander Interchange can search other yards and have it shipped.
"...For over eighty years, Hollander has been making the best tool for fast, interchangeable part matches. The new Edition Hollander Interchange contains more interchangeable options than ever before.
The Hollander Interchange provides auto recyclers and auto collectors, rebuilders, and others with the easiest and most comprehensive solution for identifying interchangeable auto parts..." See their yard Directory @: Seller Directory | Used Auto Parts | Hollanderparts
Has Vehicle Pics for some vehicles
If a specific part, such as the harness isn't listed, search again for the next higher assembly, such as in this instance, Search: 1982 >Ford > Bronco > Interior > Dash Assembly > Alternate Dash Assembly.
only one yard is listed:

Ike and Son Transmission
96502 E. U.S. 40 Craig, CO 81625
No pic

try Car-Part.com--Used Auto Parts Market
Can select certain parts
Can search by year range, such as 92 through 96 & has best item condition descriptions such as "COVER BAD LEATHER PWR BKT GRY"
Has Vehicle Pics for some vehicles incl. interior/dash, back seat, front & rear and engine bay

Check local AutoZone, etc for in-line vacuum hose connectors.
