Question about making brake/shifter cables and housings

hi all i am building my first bike from frame up.i have gotten all parts mostly used and in good shape. i have adjusted cables etc no problem before.. But i have never made from scratch. i started with a principia 650 frame with a kestrel fork that's it. I was able to piece together shimano dura ace 7800 shifters dura ace f/d and r/d.I bought Jagwire road pro cables and housing kit. So the question is... the cables housing for shifter are red and have a silver (ferrule?) end attached to it beyond that there is several inches of cable stating to brake lever .do i cut that stuff off and install the silver ferrule and that goes into shifter/brake lever??do i leave a small amount and install or do i leave the whole ?extra length completely? after that i have to figure out the length etc. but main thing is the extra cable housing past the silver end thing? to get me going. Thanks in advance!!! also running dura ace crank and dura ace cassette

The Jagwire Pro Road brake cables have a short section of smaller diameter silver housing at the end of the colored housing that is intended to reduce bulk under the bar tape. Since you want that feature for both levers, it one lever to the first cable stop and trim the housing, then use the other for the other brake lever. Gearshift housing should be the same diameter and color for the full length of the housing. The other important tip is to use good quality cable cutter and don't try to fake it with tin snips wire cutters or cheapo cutters because it will cause you grief. Also be careful sizing the last piece of housing to the rear derailleur.

Housing sells by the foot , Ferrules come in a bag of a hundred. cables come packaged as an each or the shops get Bulk Boxes ..

typical brake housing is coiled square Wire , the fancy low compression stuff has to have that braided Kevlar sheath . (made for cable disc brakes)
low compression Indexed Shifter housing Does Not ..

thank you slow joecrow and fietsbob. i kind of thought that part of cable goes under the tape. didn't want to mess up so i figured better off asking here before i regret it. am going to use a dremel to cut cable housing.when i get a chance will get them on.
