Brifter Cabling. End Cap at Brifter End or No?
Brain dead today. Can't remember, do you add a cable end cap to the end that goes into brifter?

Actually, not that complicated if you let the bike tell you.
If one fits you need it. If one doesn't fit you can't use it.

If you are using common 4mm housing, then it will generally require an end cap. In addition to supporting the end and outside of the housing, the end cap will center the housing and keep it aligned properly.
If the housing end sits at an angle, the supporting strand can migrate into the opening for the inner cable (which is usually much larger than standard shifter cable). See the effect below.

In reference to other advice offered here, don't try sticking a ferrule in a Shimano brifter brake channel. It will wedge in there and be really difficult to get out. If the brake gets used that way it can crack the brake lever body.
Shimano road brakes don't use ferrules at the caliper or lever. I don't know of any index shift system that doesn't use ferrules at both ends.

In this picture you have a 4mm shifter housing going into a ferrule for 5mm (brake) housing. Of course it works poorly.

Last time I did this I used silicone spray on the cable. Anything new or different in the last few years?

As stated, it's just to show the effect of a misalignment. If the brifter is designed to take a housing end cap, it would be even worst since the hole would be 6+mm.
