Those connect to the wiper switch assy. & work the air powered windshield washers. There are 2 inlet/outlet nubs on the wiper switch inside the steering column where they are connected to the swith to operate the washers.
If you want to resurrect that system, then I'd advise changing out all of the hoses & any brittle washers & T-fittings, etc. in the system (air from the spare tire to the washer bottle, then to column, then to squirters). You can tape the new hose to the end of the old ones, & then carefully pull through the new from the other end - in most cases. You'll then run your spare at 40 psi or the max on the sidewall, & check it often for leakage &/or washer use which empties out some air over time. IMHO an ingenious & lightweight system from something everybody should carry - a spare tire!
If your 914 was converted to an electric pump washer, then those were abandoned in place.
